102 questions, each answered in full.

A pair of AI glasses with a camera that can record audio offline.

It takes 4K photographs and five-second clips, and it can be set on your phone to take one every three seconds and string them into a sequence by itself. It records audio at the same time, and the recording is written to the glasses' own storage without touching the network at any point — no signal, aeroplane mode, phone left at home: it records anyway.

It is a pair of glasses first: a TR90 frame, built to a traditional optical structure, with UV400 lenses; myopia, hyperopia and astigmatism can all be fitted.

Four things.

One. Offline recording. There are AI glasses with cameras, and there are audio glasses that record; doing both at once, with the recording depending on no network at all, is at present only this pair.

Two. The main microphone is on the lower rim. The port faces down towards your mouth, only 4–7 cm away, so you can speak very quietly.

Three. Three sizes. Not one standard size made to fit by flexible temples.

Four. It is a good pair of glasses in its own right. Strip every electronic part out and it is still a four-figure pair of glasses.

Because on those other glasses the recording is essentially the microphone being lent to the phone — the audio goes over Bluetooth and the phone does the storing. No phone, no signal, aeroplane mode, and nothing is kept.

Ours is written to the glasses' own storage, touching neither Bluetooth nor the network at any point. In the mountains, on the underground, on a plane with the phone switched off — you press once and it records. Sync when you are back within reach of a network.

Photographs work the same way: taking one does not need the phone connected. The glasses store it first and send it later.

No, and that is deliberate.

At the hardware level it records only the person wearing it — a few people brainstorming, an interview, a lecture: this pair cannot do that, and a voice recorder is the right tool for it.

Online meetings it can. If you want your own half of what was said in a meeting kept separately, it is exactly right — what it records is the part you said.

No screen, and not AR. It projects nothing in front of your eyes.

What we build is the input layer: getting what you say and what is in front of you down cleanly, and handing it to the phone. What it then becomes can wait until you are back at a screen.

On the phone.

Locally the glasses do two things: pick up sound and frame a picture. They do not read, do not understand and do not reason about anything.

That division of labour is deliberate. It lets the hardware be small, frugal and cheap, and it lets the model be swapped for a better one at any time — rather than being locked to a chip from two years ago.

MYSK App, our own. It is the first thing the hardware pairs with — pairing, fetching photographs, fetching recordings, managing the device.

The glasses are bought once. There is no monthly fee.

They are renders.

More of the detail will be decided by a vote of the first 1,000 people who order. That is what taking part in the pre-sale gets you: not only the glasses sooner, but a hand in the details of the design.

Because continuous video is a bad form on a pair of glasses, and each of its three problems is bad enough on its own.

It shakes the whole time. The rise and fall of your head as you walk never stops, and stabilisation rescues some of it, not all. Two minutes into a ten-minute recording from a pair of glasses and you feel sick.

It is too big. 4K at thirty frames is one to two GB every five minutes. Storage has to grow, the battery has to grow, and the heat has to go somewhere — the three most expensive kinds of space on a pair of glasses.

Nobody watches it twice. An hour outdoors recorded as an hour of video is an hour of material you will never open.

This is not a feature removed. It is a way of thinking about the product.

Use interval shooting. Set it on your phone — one every three seconds, say — and it keeps going by itself.

What you get back is a short film with a rhythm rather than a running account. The shake is gone: every frame is an independent still, and the phone aligns them afterwards, which is steadier than continuous video can be. It also does the selecting for you — an hour compressed into thirty seconds, without you spending an hour cutting it.

There are five-second clips too, for when something has to move.

Storage came down from thirty-odd GB to a few, and the battery did not have to grow for continuous encoding. Both of those went into the sensor and the lens.

Storage is also getting more expensive this year, and the thing that eats the most of it is exactly continuous 4K video. Leaving it out saves more than space; it saves real cost — and that lands, in the end, on the price you pay.

Because on a sensor this small, pushing the pixel count up is the easiest and least useful thing anyone can do.

Over the same area, more pixels means each one is smaller; and how much light a single pixel catches decides the noise in low light and how much detail the highlights and shadows can hold at once. Packing twenty megapixels into the same area means each pixel catches half the light. A better spec sheet, a worse photograph.

So we spent the budget in the opposite direction: a larger pixel. A 4K photograph out of 12 megapixels is more than enough on a phone, on a social platform, or printed at six inches.

Allwinner V883. Quad-core CPU, 4 TOPS on-device.

But what matters is not those two numbers; it is which jobs are done inside the chip: AI-ISP (noise reduction, wide dynamic range and colour all settled at the moment of capture), PDAF phase-detect focus (raise your hand and press, without waiting for it to hunt), electronic stabilisation (you are shooting while walking, not while braced), and 4K encoding.

What a flagship phone chip is good at is running a large model on the device itself. Our AI is not on the glasses; it is on the phone.

So what we want is not a chip that thinks, but a chip that gets the frame down clean — AI-ISP, phase-detect focus, electronic stabilisation are the three that decide what the picture looks like. The cost and the power we did not spend went into the sensor, the lens and the battery.

A wide aperture, an ultra-wide angle, a fixed focal length, and a multi-element hybrid glass-and-plastic group.

Fixed focal length: glasses do not need a zoom — turning your head is the zoom. A zoom means a motor, a longer barrel and more moving parts, all three of which add weight, cost power, and give something to break.

Ultra-wide: because you have no viewfinder. Raising your hand and pressing, you are not sure where the edges are — go wider and you will not cut off half of someone's head. Capture it first, crop it on the phone.

Wide aperture: it decides whether dusk, indoors and the shade under a tree — the not-very-bright places you still want to photograph — remain usable at all.

Hybrid glass and plastic: all-plastic elements are cheap, but the edges go soft and pick up purple fringing. A glass element holds both down, at the price of a little more cost and a little more weight. We accept that price.

No. They are stored on the glasses first and synced later.

Yes. It is lit while it shoots and dark when it does not, beside the camera, facing outwards, not towards your eyes. It is not a setting that can be turned off.

We changed our minds about this one. On the recording-only version we took every light off the device, on the grounds that those glasses physically could not record the person next to you — where there is no problem there should be no warning either.

A camera has no such property. It photographs wherever it points, and you cannot design a lens that captures only what you are looking at and never anyone else. The boundary can only be drawn by people and by rules, which means the people around you have to be able to see the state. The premise changed, so the conclusion had to change with it.

The camera faces what is in front of you, the same as your own eyes. It is meant for outdoors and for being on your own.

Please respect the rules of wherever you are — exam halls, secure sites and some museums do not allow camera devices.

No.

Both microphones are on the frame: the main one at the middle of the lower rim on the left, its port facing down towards your mouth, 4–7 cm away; the reference one at the top of the right rim, its port facing up and away from your mouth, much further from it. The decision is the difference in level between them, and someone half a metre away never reaches the threshold.

This is not a software filter — it is where the ports are. A physical guarantee is worth far more than a promise in software: a promise can be quietly changed in the next firmware update, and geometry cannot.

Quietly enough that someone half a metre away cannot hear you, and it still records you clearly. That is what the 4–7 cm between the main microphone and your mouth buys.

Because the temple is too far from your mouth. Sound pressure falls off quickly with distance, and the gap between a few centimetres and a dozen is not a small difference — it is the difference between keeping other people out by position alone and not.

On the temple you have to use an algorithm to guess which words are yours, and when the algorithm guesses wrong you do not know it guessed wrong.

In the glasses' own storage. Nothing touches Bluetooth or the network while it records.

When to sync, and where to, is yours to decide. What you said is yours.

At the hardware level the recording captures only the wearer — what the child says is recorded, what the classmate beside them says is not. That is the same answer for a parent and for a school.

The camera side is different: that boundary has to be kept by people, which is why the indicator light is always-on by rule and cannot be turned off. Check the school's rules before taking it in.

Because a device you do not want to wear is worth nothing, however much it does.

Frame, temples, hinges and nose pads are all built the way the high-end sports and children's eyewear sold in the United States is built. Strip every electronic part out and it is still a four-figure pair of glasses — one that holds up indoors, and outdoors in sport.

To be exact, what we use is a hybrid: TR90 for the body, titanium for the hinges and the trim. Neither all titanium nor all plastic. The next question has the full comparison.

Three reasons for not making the body titanium. The first two are engineering; only the third is weight.

One. There is a microphone hidden in the front frame, and electronics in both temples. Running a flex cable through a metal frame is a harder problem, and we could not find what it would buy us.

Two. Metal fights the antenna. There is WiFi and Bluetooth Low Energy in this pair, and the antenna has to radiate outwards. A metal frame shields it and detunes it, and keeping the antenna alive would mean a stack of structural concessions — concessions that cost more than titanium is worth.

Three. TR90 suits this use better. It is the nylon used in high-end American outdoor sports eyewear: very light, very resilient, springing back under load instead of deforming; it does not conduct heat, so it is neither hot in summer nor cold in winter; and it contains no nickel, so it rarely provokes an allergy. It is not the cheap plastic the word "nylon" brings to mind.

What titanium is genuinely better at is being adjusted with heat, and that sense of luxury. But this is a pair worn a dozen hours a day that goes out into sport with you — what we want is durable and light.

Because the two roads solve different problems. All titanium is the best answer for a traditional pair of glasses, and what we have to fit is a pair with a battery, an antenna, a speaker and sensors inside. On four dimensions the hybrid suits it better.

So what is the titanium still for? The two places that need it most: the hinges and the trim. The hinge is where glasses actually break, and it needs the strength and the precision of metal; the trim is where the quality is felt — the shine and the touch of metal are things a moulded part cannot imitate.

In one line: the structure and the electronics go to TR90, the loads and the feel go to titanium.

Because what the two need is entirely different: one puts function first, the other looks.

What TR90 is good at: very high elasticity and impact resistance — it springs back after bending, and it rarely breaks when dropped, sat on, twisted or knocked; it is typically thirty to fifty per cent lighter than acetate; it does not shatter into sharp pieces, which lowers the risk of a second injury to the eye and face; it stands up to sweat and heat without deforming; and it contains no metal or nickel, so the risk of an allergy is low. TR90 was designed for sport and impact in the first place.

What acetate is good at: rich, layered colour with real grain and depth of shine, and a thick, expensive feel in the hand; and it can be adjusted precisely with heat, so an optician can fine-tune the fit.

What acetate costs: it is harder and more brittle, so it cracks or snaps under impact; it is noticeably heavier; and it deforms more readily in heat. It does not suit frequent hard exercise, and it does not suit the rough handling of a child.

Neither is simply better than the other; they are for different uses. What the high-end sports brands use is usually a better TR90 formulation, not ordinary injection-moulded plastic.

Thin, and wide — the feel of a fashion sunglass temple. This is a balance struck in three directions.

Thin so it does not look clumsy. Electronics packed into a temple most easily become a bulge, and a bulge stops it looking like a pair of glasses.

Wide so there is room to lay the electronics out flat instead of piling them up. For the same volume, laid out looks far better than stacked.

Wide also solves something else on the way: it shades the outer corner of the eye. Ultraviolet arriving at an angle from the side is the part most glasses miss, and a wide temple simply blocks it.

But we do not wrap it. A wraparound like a pair of goggles would seal the eye better, at the price of a frame that has to be thick and heavy. Block what should be blocked, without stacking weight on for the last few per cent.

Liquid silicone, in an air-cushion shape, and replaceable in two heights. Sports eyewear generally does not use metal nose pads, for five reasons.

One. They slip once you sweat. A metal pad is hard and smooth, and once you sweat heavily the friction drops sharply and the glasses slide down. A soft pad does the opposite — wet, it grips better.

Two. They are safer in an impact. In hard exercise or a fall, a metal pad presses into the bridge of the nose and can injure it; a soft pad cushions.

Three. They are more comfortable. Worn hard for a long time, metal pads leave marks and red patches on either side of the nose, and sometimes hurt. Soft pads touch over a wider area, sit closer, and spread the pressure more evenly.

Four. The structure is different. Sports eyewear uses a one-piece soft pad, a height-adjustable rubber pad, or simply the fit of the whole frame — designs that suit fast movement, sweat and vibration.

Five. Allergies and wear. Some people react to metal, and skin is more sensitive during exercise; a soft pad also does not oxidise and darken.

Everyday metal frames use metal pads for adjustability and for the sense of luxury. What we put first is grip, cushioning, comfort and safety.

Yes, and the spares are in the box. The height of the bridge of the nose varies enormously from person to person and one size cannot suit everyone — a high bridge takes the low pad, a low bridge the high one.

This is also the main mechanism by which the same frame suits both Western and Asian faces: the largest difference between them is not head circumference but the height of the bridge and the depth of the face.

Because in the paint shop, one colour and five colours are not the same problem. Concentrating the first run on a single colour is what keeps the finish consistent.

Other colours will come, but not in this first run.

Two reasons.

It is the one colour that does not play the contrast game against skin. A dark frame sets up a strong contrast on pale skin, and a pale frame is swallowed by dark skin. White is the colour that goes wrong at neither end — pale or dark, a white frame simply frames the face cleanly. For a product that has to meet Western and Asian faces and every skin tone, that matters far more than being pretty.

It is also the hardest on the process. Any shift in shade, any orange peel, any build-up of paint at an edge is impossible to hide on white. We use the same baked finish as the classic Apple phone white — choosing white means accepting a lower yield.

Among AI glasses of this class it is one of the lightest. We do not say "the lightest" — that word is fought over by fitting a smaller battery and cutting more features, and whoever wins it cannot hold it.

The three sizes do not weigh the same: S is the lightest and L the heaviest. We will publish the measured figure for each size before shipping, rather than covering three sizes with one number.

Mostly not through materials, but through the decision to take photographs and not long video.

Continuous 4K encoding runs the chip flat out for long stretches: power goes up, the battery has to grow, the heat has to be handled — and the battery is one of the heaviest single parts in a product like this, with the thermal structure and its metal a second bill. The three together weigh far more than the camera module itself.

We only take photographs, so the chip can drop back into deep sleep between two of them, an order of magnitude lower in power. The battery does not have to grow and nothing has to make room for cooling.

Rinse first, then wipe. Never wipe it dry. The commonest cause of a scratched lens is wiping it while the dust is still on it, grinding that dust across the coating. Rinse under cool water, then dry with a cloth. Do not use alcohol or household glass cleaner; they take the coating off.

Do not leave the glasses on the dashboard of a car. Heat softens TR90 and the frame distorts, and a distorted frame moves the main microphone away from your mouth — the one distance this product depends on most.

The microphone port is a very small hole with a metal mesh behind it. The day a recording sounds muffled, look at that hole on the lower left rim first. Rinse it; do not poke anything into it.

The prevailing approach is one standard size per model, relying on flexible temples to suit most faces. That is a reasonable approach: tooling costs less, stock is simpler, the pitch is cleaner, and flexible temples really do cover a fair range.

But there is only one dimension it can adjust — how far the temples splay.

It cannot adjust the width of the frame, the width of the bridge, or the height of the lens. And those three decide where the glasses sit on your face: too wide a frame slides down; too wide a bridge puts all the weight on two points; too tall a lens catches on the cheekbone.

Headphones can be made in one standard size, because you wear them for a few hours and can take them off at any moment. Glasses are not that. They press on the bridge of your nose and rest on your ears from the moment you leave in the morning until you get home. On that timescale three millimetres is not "slightly off" — it is the two red marks on your nose at the end of the day, and it is you deciding not to take them next time.

That is another road, and it makes sense too: several shapes and colours solve the problem of taste, so that people with different styles each find their own.

We spent the same tooling budget on fit. The reason is that this pair is not purely a fashion object: it has to be worn a dozen hours a day, worn outdoors in sport, and worn by a six-year-old. In those uses, staying wearable comes before looking good.

And having only one colour is what lets us get the finish on that one colour right. Do one thing in the first run, and do it properly.

Size S　Frame width 132 mm, frame height 42 mm, lens width 48 mm, bridge 17 mm, temple length 130 mm. For reference: children of 6–12 and some smaller-headed teenagers, head circumference 48–54 cm, face width 115–132 mm.

Size M　Frame width 149 mm, frame height 50.6 mm, lens width 53 mm, bridge 21 mm, temple length 157 mm. For reference: teenagers to adults, head circumference 53–59 cm, face width 130–150 mm. This is the size that corresponds to the standard the AI glasses on the market are built to.

Size L　Frame width 163 mm, frame height 57 mm, lens width 56 mm, bridge 22 mm, temple length 165 mm. For adult men with noticeably larger heads and wider faces, and for some wider-faced women; head circumference 57–63 cm and above, face width 145–165 mm.

All of these are measured by hand and may be slightly out. On top of the three sizes there are flexible temples, so the real coverage is a little wider than these ranges.

Measuring your head is the most accurate. You can also send us the string of numbers printed inside the temple of the glasses you wear now and we will match it — that string is usually lens width, bridge width and temple length.

Identical. The same camera, the same two microphones, the same speaker, the same lens options. The only difference is the size.

The small size is not a children's version with features taken out.

Yes, mainly through the replaceable nose pads. The largest difference between them is not head circumference but the height of the bridge and the depth of the face — a high bridge takes the low pad, a low bridge the high one, and the same frame lands in the right place on both faces, sliding down neither nor touching the lashes.

Yes. The shape runs along the line between round and square, with neither a sharp cat eye nor a hard rectangle.

With three sizes on top of that, one design reads as a different character on a different face, rather than one pair of glasses forced onto everyone.

No, and that is one of the reasons we chose white. A white frame does not play the contrast game against skin at all: pale or dark, it simply frames the face cleanly.

And light red gold is a warm colour, which lifts any skin tone rather than weighing it down.

Yes, but it is not a separate children's product; it is that the smallest of the three sizes happens to land on the face of a child of six to twelve.

And once it lands there it becomes something else — the first pair of children's AI glasses in the world that both take photographs and record offline. AI glasses, not AR.

There are children's watches with cameras, and there are children's devices that record. But a pair of glasses that lets a child photograph a flower, an insect or a leaf out in the open, depending on no network at all, is something nobody had made before.

An incidental result is that a family of three can have one each: the small size for the child, the medium and the large for the adults.

The hinge. So the hinges in all three sizes are built to sports-eyewear standards, and the small size especially.

One plano light red gold lens, in Trivex, at no extra charge.

That is the only one included. The aim is for a white frame with a light red gold lens to become the mark of our community and its culture — recognising each other in the street is a matter of what these glasses look like.

Any other lens colour, or a prescription, is paid for separately.

Trivex is one of the best lens materials there is, better than the 1.60 (MR-8) that high-end glasses usually use.

The best impact resistance, which is why it is what high-end American sports eyewear and children's eyewear are made with — the two uses most sensitive to whether a lens shatters.

Lighter than ordinary resin, with less optical distortion.

A lens in this material is mostly ¥400 to ¥800 or more at an optician, and it is what we ship as the default, free.

Three layers of reason: the mark of a community, the widest range of uses, and a whole set of practical benefits.

The most direct one first. As the first model to go on sale, we wanted it to have a look that can be recognised. A white frame with a light red gold lens is itself the mark of our community — which is why only that one lens is included.

It suits every skin tone and every age. The paler traditional sunglass tints are usually grey, green, brown or tan — their virtue is that they do not change the colour of the world, and they are lighter than black. We did not choose any of them, because they are also what most people pick for photochromic lenses, with the result that in front of a camera those colours read as middle-aged.

Light red gold is plainly different. It lifts the whole face at once: younger, more current, more alive.

But it is not only about looks. What follows is why we really chose it.

One. The lens itself is UV400, against UVA and UVB, and it filters blue light.

Two. It is unremarkable indoors and out during the day, because the tint is very light. Walking in from outside, it does not stop you seeing indoors.

Three. It is the mark of the community. A white frame with light red gold is recognised in the street at a glance.

Four. You can keep it on all evening — housework indoors, walking about, working: none of it is a problem.

Five. You can use your phone normally, and it blocks the phone's blue light as well. That matters especially on a pair of AI glasses: outdoors you are forever pulling the phone out for a look, and a dark tint is a nuisance at exactly that moment.

Six. It is particularly useful indoors when you are out. Restaurants, shopping centres and airports are full of artificial light, with a great many lamps in them.

Mainly artificial blue light.

Blue light from the sun actually does people good, and at night there is none of it anyway, so it does not touch melatonin. What causes trouble is the short wavelengths of artificial blue light — and we hold that it should be filtered by day and by night alike.

At night what wants filtering is not blue light alone but the whole short end: blue, green and violet.

Some lenses on the market claim to "filter the harmful blue light and keep the beneficial blue light", separating them by wavelength. That does not match the thinking of the American biohacker community — the consensus in the biohacker and longevity community in the United States is that artificial blue light is bad for the body whatever its wavelength, because it affects not only melatonin in the eye but the microbial layer of the skin.

It should be said plainly: this is that community's position, and the position we adopted in making our choices. It is not a settled medical conclusion.

It is. To block blue and green light at night, deep red and true red really are the most effective.

We did not choose them for a very practical reason: worn at night, deep red and true red make it very hard to see anything, and worn by day they look strange, because the colour is simply too red.

Light red gold is the compromise that holds up by day and by night, indoors and out.

Because you will not take them off when you walk in.

Sunglasses have exactly one pattern of use: put on when you go out, taken off when you come in. That is precisely why a sunglass lens can be as dark as the sun demands. This pair has a pair of headphones and a camera inside it, and that pattern breaks in two places.

Indoors you cannot take them off. You may be in the middle of a call, or halfway through listening to something. Taking the glasses off means interrupting it — and forcing someone in a doorway to choose between hearing and seeing clearly is a bad thing to do. So the lens has to be liveable under a ceiling light, and a dark one is not.

Outdoors you still have to look at your phone. Fetching photographs, going through the album, changing a setting: all of it happens outdoors, in sunlight, on a screen. A dark lens pushes the glasses up onto your forehead every single time — and the moment they go up, the main microphone leaves your mouth. A light lens shades your eyes without shading your screen.

In bright light a light tint does more than that sounds: it takes off the layer that makes you squint, until you stop thinking about it. For a pair of glasses you have no intention of removing, that is what you actually want.

Yes: photochromics. That is the complete answer to the doorway problem — clear indoors, sunglasses outdoors, without you doing anything.

The molecules in a photochromic lens change shape when ultraviolet reaches them, and in that shape they absorb visible light, so the lens darkens; take the ultraviolet away and they relax back, and the lens goes clear again. No power, and no switch.

It suits this pair particularly well, because you never have to push the frame up onto your forehead — and the moment you do, the main microphone leaves your mouth. Photochromics can be made with a prescription too.

Because you have to look at your phone.

What a polariser removes is light reflected off a flat surface at a particular angle — water, wet roads, a car bonnet. That is genuinely useful for fishing and for driving.

But what a phone or a laptop screen emits is polarised light. Put a polariser in front of it and the screen dims, and at some angles it goes black as you turn your head. Every sync, every look at a photograph, the lens is working against you.

Polarised lenses are made for looking at water. This is a product made for looking at a phone.

We asked a great many fashion creators, and the answer was consistent and blunt: a gradient reads as middle-aged. It is a permanent band of darkness, and it turns up in every photograph of you.

Photochromics are the version of the same idea without that baggage — most of the time a clear lens, and a pair of sunglasses when there is sun. Nothing about them is permanent.

There is no restriction. Everything a professional optician can order, these glasses can take:

Myopia at 0–300, 300–600 and above 600; hyperopia; astigmatism at any power; progressives; photochromics; photochromics with a prescription; tints; tints with a prescription; high-index materials; unusual pupillary distances.

You think it is the late nights, you think it is bad sleep. In fact you may already be slightly long-sighted.

For some people it starts at thirty-eight, for some at forty-five, for some at fifty; it varies a great deal. And the awkward part is this: if you need a prescription in your thirties or just past forty, you do not want people to think you are wearing reading glasses.

But what you are wearing is a pair of AI glasses. That changes the whole thing.

Have it measured at an optician once; that is the most accurate. Or, more simply, try the ready-made ones in a shop: whichever is comfortable is the one for you.

Hyperopia usually does not change much, and most people are not far apart from one another — which is where it differs a great deal from myopia.

The real problem is that if you never wear anything, you never notice. Suddenly not being able to read small print does not arrive as the thought "I should get glasses"; it arrives as a slowness seeping into your work, your reading and your life: the menu read twice, the instructions skipped, the phone's type size going up and up, reading at night getting more and more tiring.

Either works.

Progressives: distance power above (or plano), near power below. One pair of glasses for two jobs.

Two pairs: one for distance, one for near. Some people simply never get used to progressives — the edge of the field swims, and going downstairs means tilting your head to find the angle. So two pairs is where a good many people end up.

By material and by power, from ¥60. Tints are 1.2x the clear price and photochromics 1.5x. The clear tier includes blue-light filtering and a UV coating.

0–300: 1.56 ordinary resin from ¥60 / 1.60 (MR-8) from ¥100 / Trivex from ¥180.

300–600: 1.60 (MR-8) from ¥100. 500–800: 1.67 (MR-7) from ¥180. Above 800: 1.74 (MR-174) from ¥360.

The same lens is usually ¥100 to ¥2,000 at an optician in China, and $50 to $800 at LensCrafters or a Walmart Vision Center in the United States. Those are published list ranges given for comparison only; they are not a quotation from any particular shop.

Astigmatism, progressives and unusual pupillary distances are priced separately. Send us the prescription and we will confirm it before cutting.

Yes, and that is something we kept on purpose.

The frame is built to a traditional optical structure, not a sealed part that only takes the manufacturer's own lens. Walk into any professional optician with it and everything they can do, they can do on these glasses.

Tell them it is a TR90 front frame in ordinary indoor-spectacle proportions, and ask them not to force the rims open while the temples are attached.

Sphere (SPH), cylinder (CYL) and axis (AXIS) for each eye, and your pupillary distance (PD). Your optician has them, and most prescriptions print them directly.

Then tell us whether you want that prescription clear, tinted or photochromic. If you are not sure, leave it for now: put a note on the order, or simply send us a photograph of the prescription.

Three things worth knowing before you order them.

Behind a car windscreen they barely darken at all. Laminated glass blocks most of the ultraviolet, so the lens never gets the signal. If you mostly want them for driving, have a fixed tint instead.

Temperature changes them. In the cold they go darker and clear more slowly; in the heat they never reach their darkest, but they clear faster.

They do not go completely clear indoors; a trace of colour remains.

No — and this is a genuinely harmful misconception.

Ultraviolet protection comes from a UV400 coating or from the lens material itself, and has nothing whatever to do with how dark the tint is. Darkness is comfort; protection is chemistry; the two are independent.

A dark lens that does not block ultraviolet is more dangerous than no glasses at all: the darkness opens your pupils, and wider pupils let more ultraviolet reach the back of the eye than would get in unshaded, with the pupils contracted. The cheap ones on a street stall are usually exactly this, and holding them up to the light tells you nothing.

Every MYSK lens is UV400 — the one included, and any prescription lens we cut. There is no version of this product in which protecting your eyes is an upgrade.

Yes. All the electronics are in the temples, so a new set of lenses for the front frame costs what the lenses cost. You can have one fixed tint and one photochromic and change them with the season.

You look at the code on the till and the payment is done. No phone out, no unlocking, no app opened.

In every country and region Nihao Pay supports, currently China, the United States, the Middle East and Southeast Asia.

Which countries and regions are actually available follows Nihao Pay's coverage.

Within China only Alipay has built this into a pair of AI glasses. Outside China, no payment app has brought it into AI glasses at all.

Working with Nihao Pay, it is available in all four markets at once.

"The first" is what we know to be the case as this is written.

Nihao Pay is an ecosystem app on MYSK.

At the same time, MYSK is an ecosystem partner in Nihao Pay's payment ecosystem.

Each is a part of the other's ecosystem.

This first run is made for users in mainland China and the interface is Chinese only.

Chinese speakers abroad can still buy it and use Nihao Pay for small payments without a passcode. How it ships outside China is something we work out one to one once you have joined the community.

The platform is open: phone apps, desktop apps, even purely web-based ones can all join.

The glasses get the picture and the sound down cleanly, and the rest goes to whoever does that thing for a living — finishing photographs, taking notes, keeping records, paying. We do not intend to do all of it ourselves. The full list will be announced as it grows.

DOKA Camera is an ecosystem app on MYSK.

The glasses get the picture down cleanly, and finishing it goes to the people who do that for a living.

No. Shooting, organising and exporting are free; only the advanced features need its own super VIP.

The interface documentation and a development kit: how to connect, how to fetch photographs, how to fetch recordings, how to trigger the shutter. What a developer gets is the same set we use ourselves. The documentation goes public before shipping.

Other people's things. A user's photographs and recordings belong to the user, not to us and not to any third-party app. What a developer receives is the copy the user has authorised, not a back door.

These we do not intend to build ourselves, and all of them are buildable:

Identifying plants and animals in the field. A child sees a plant they do not know on a hillside, presses once, and comes home to a named list with pictures.

Picture notes. A line or two attached to each photograph, spoken or written.

Time outdoors. An app that does one thing: record how long you really spend outside each day.

A food diary. Twenty photographs across an hour of a meal, becoming a record of what you ate by itself, and something a health analysis can work from.

¥1,250 retail. An early-bird code takes ¥400 off, for an early-bird price of ¥850.

One plano light red gold Trivex lens comes with it at no charge. Another colour, or a prescription, is paid for separately, from ¥60. Free shipping throughout mainland China, with no packaging or handling fee added.

The pre-sale opens on 21 August 2026 and it ships on 30 November 2026.

Yes. You pay now and it ships on 30 November 2026.

If we are more than sixty days later than that, we refund you without your having to ask.

Because many people's lenses are cut to their own prescription, and it is sent once they are made. This is not a matter of efficiency; it is what the business of fitting glasses has always looked like.

The first run goes to mainland China only, with free shipping throughout.

Nowhere else for now — every market needs its own radio certification, and shipping abroad needs a warehouse there. We would rather do one place properly first. If you are abroad and want one, join the community and we will work out one to one how to get it to you.

The glasses (with the plano light red gold lens already fitted), replacement nose pads, a magnetic charging cable, a case and a cloth.

No.

MYSK has no brand tie and no co-branding of any kind with the Musk Institute, with Elon Musk's father, or with any member of the Musk family.

The only link is a donation: for every pair of AI glasses MYSK sells, ¥10 goes to the Musk Institute. And the Musk Institute is the new platform Elon Musk's father, Errol, started late in his life.

That is all of it.

A research body founded by Elon Musk's father, Errol Musk. It is not Elon's project, and it has no connection to SpaceX, Tesla or xAI.

It began with a conversation in Dubai in late 2024. Someone asked him what he would do next, and he answered as an engineer: getting rockets right is not enough, there is also travel through space and time, and conquering gravity, to work on. Someone in the room said: then why not call it the Musk Institute.

Four directions: longevity, fusion, spacetime, gravity.

Its idea is not to recruit the scholars with the best CVs, but to find the people the system does not recognise who have strange, original things in their heads — the "undiscovered Faradays". Children included: some of them may be building four-dimensional space in their minds and simply have no language for it yet.

The address is www.muskasi.com.

For every MYSK sold: ¥10 to the Musk Institute and ¥10 into the MYSK stray cat fund. No cap, and no sales tier attached.

Which grassroots rescues the stray cat money finally goes to is decided together by the 30 launch partners, and the accounts are public.

A place in the Musk Institute's first cohort.

In its first year the Institute admits no students, teaches no courses, raises no funds and runs no commercial activity. The one thing it does is travel the world with Errol Musk: a tour of China first, then Japan, Dubai, Southeast Asia, and a Starship launch watched in the United States.

The first cohort comes entirely from MYSK owners, limited to the first 1,000. The place can be transferred — if you cannot go yourself, you can pass it to someone else.

The community organises the itinerary itself. How each city is done, where to go, where to stay, is worked out among the members. We are not a travel agency.

All of Errol's costs are borne by us, and are not spread across any member of the cohort.

Whoever is going to a given stop meets first in the group chat and talks through the route and what to do together locally. On the day, Errol leads.

That can only be fixed close to the time. It falls during the summer of 2027, at Starbase, beside Boca Chica Beach near Brownsville, Texas.

We do not pin the date a year ahead. SpaceX's schedule moves constantly and any launch date fixed a year in advance is not credible — we will tell you the moment we can be sure.

The good news is that the launch rate keeps rising. Going to Texas to watch a launch is far more likely to come off than it was a few years ago, when it meant betting on a window that opened once every few months.

What we cover: the ticket to the launch viewing party; and no charge for the organised service, the local guide, the party itself, or arranging the private tour. We will invite some former SpaceX executives and engineers to the party.

What you cover: flights, hotel, food, local transport, visa and insurance.

He might; we cannot say he will. Errol Musk is leading the trip and that is certain; Elon is not, and it is outside our control.

Please do not treat it as a promise, and do not make it one to anybody else.

No. It is a viewing trip we organise, and we are not a SpaceX partner. There is no commercial relationship between MYSK and SpaceX or Tesla.

Delay is normal, not an accident. Weather, a technical check, airspace — any of them can push a launch back days or weeks.

Leave slack in the itinerary, and book flights and hotels you can change.

A mainland passport needs a B1/B2 for the United States, and an interview can be refused. This is outside what we can help with; please weigh it up yourself before signing up.

You share an invite link or an invite code. Your audience arrives through it, picks up a ¥400 early-bird code, and it comes off automatically at checkout: they pay ¥850.

You take 30% of what they pay, ¥255 an order.

There are 30 of them. They are also trustees of the Musk Institute.

Over the ten weeks from 21 August to 30 October 2026.

Each week, the top three on the referral leaderboard become launch partners. Anyone who is already a launch partner drops out of the leaderboard for the following weeks — so three new launch partners appear every week.

Ten weeks x three a week = 30 launch partners.

Yes. The commission and the leaderboard are two different things — you simply stop occupying a place in the following weeks, so that new people have a chance to come up.

Two different things; do not mix them up.

Launch partners: 30 of them, three a week from the creator referral leaderboard, and they are trustees of the Musk Institute.

The first cohort: the first 1,000 people to buy the glasses, and what they hold is the right to travel the world with Errol Musk. The place is transferable.

Attribution: last click, thirty-day window. A cookie and your own code both count.

The base: what the buyer actually pays for the goods, excluding shipping and tax.

Refunds: the commission on that order is reversed, and only that one.

Settlement: it follows shipping, and is settled after the November 2026 despatch. That way neither of us carries the refund risk of a three-month pre-sale window.

You decide. We do not review your work, and we will not ask you to say the product does something it does not.

The only requirement is that commercial content is labelled as the platform requires: Xiaohongshu through Dandelion, Douyin through Xingtu, every other platform under its own rules.

A few things, and they are there to protect your own account.

Do not pin down the name or the date of any particular launch. SpaceX's schedule moves constantly, and if you have pinned it and it moves, you are the one who gets called out.

Do not imply that MYSK has a commercial relationship with SpaceX or Tesla. It does not.

Do not say Elon Musk will be there. Errol is leading the trip and that is certain; Elon is not.

Do not say "the lightest". What we say is "one of the lightest in this class".

Put "this is a pre-sale, shipping 30 November" somewhere people will see it. Three months is not short, and letting someone find out afterwards costs far more than saying it beforehand.
