Fitting a computer into a pair of glasses creates an awkward design problem: the electronics need room, but the result still has to belong on someone’s face. Povilas Grigas approaches that tension without pretending it can disappear. His Glasses concept gives the hardware a deliberately different silhouette, treating smart eyewear as its own design category rather than ordinary frames with a technological secret. I like that starting point.
Developed for his 2024 design BA thesis, the mixed-reality concept imagines an alternative to being tethered to a phone or desktop screen. The ambition is to make computing available through something worn rather than something you continually look down at or sit in front of. That’s an appealing proposition, although moving digital information closer to your eyes doesn’t automatically make it less demanding of your attention.
Visually, these glasses have enough personality to carry that discussion. The broad, rounded lens openings sit within a flowing silver-colored frame, while the bridge has two dark circular elements above an oval opening. In the front view, that arrangement almost resembles a tiny surprised face. It’s an unexpectedly playful detail in an otherwise polished object. To my eye, the overall effect lands somewhere between sculptural eyewear and a science-fiction costume department with unusually good taste.
Grigas specifies CNC-milled, polished grade 5 titanium for the frame and optically polished sapphire crystal for the lenses. Those are proposed material choices, not evidence that the finished glasses would feel featherlight or survive everyday abuse. Still, I appreciate the intention behind them. A computer worn this prominently deserves the material attention we give a watch or a favorite pair of glasses, especially if the expectation is that it becomes part of someone’s daily appearance.
The frame’s outline follows the bones around the eyes, according to Grigas, and the vision sensors occupy the bridge for a centered point of view. That placement gives the front a clear organizing feature. Rather than scattering visually competing details across the brow and corners, the design concentrates its most conspicuous technology near the middle. It’s a convincing composition, even if a convincing composition is only one part of making wearable computing practical.
From the side, the arms look substantial, with long, smooth surfaces that curve downward behind the ears. Their thickness is part of the visual identity rather than a detail the presentation tries to conceal. I’d rather see that volume handled deliberately than watch a designer chase thinness at the expense of the overall shape. Here, the broad arms and generous front feel like parts of the same object.
The personal question is whether I’d want such a distinctive object defining my face every day. I’m not sure, and that uncertainty is worth keeping in the conversation. Glasses are unusually intimate technology because people look through them while other people look at them. A frame can be beautifully resolved and still feel wrong for an individual wearer. I’d want more than an impressive image before deciding these belonged in my routine.
The proposed leather charging case helps make that routine easier to imagine. The glasses fold flat inside it, and the presentation shows a dark, textured exterior with visible stitching and a circular metal closure. It reads as an eyeglass accessory rather than a miniature electronics bag. More importantly, putting the glasses away feels like a recognizable action. I find that more reassuring than an expectation that a wearable computer should remain on your body indefinitely.
For now, this is an academic design proposal, not a demonstrated replacement for your laptop. Its presentation doesn’t establish battery endurance, display quality, or long-term comfort, so those questions remain open. What earns my interest is the willingness to give computing a visible presence without making the frame look apologetic. I wouldn’t ask these glasses to pass as ordinary eyewear. I would ask whether their eventual usefulness could earn the space they occupy on my face.

EDITOR'S QUOTE:
The INMO GO3 AI Glasses pair familiar eyewear styling with practical translation tools and the convenience of swappable batteries.
Looking down at a phone to translate a conversation can interrupt the exchange it’s supposed to help. Reading presentation notes creates a similar problem, pulling attention away from the people in front of you. The INMO GO3 AI Glasses bring those words into view instead, putting translation and presentation tools inside a familiar rectangular frame that doesn’t require a dramatic change in personal style.
That familiar shape is only part of the appeal, though. Adjustable contact points, discreet controls, and, most importantly, a replaceable battery give the GO3 a practical foundation beyond its display. Together, they suggest an approach to smart glasses that puts everyday wear on equal footing with software features. How convincingly the GO3 brings those priorities together comes down to a few details, starting with the frame itself.
The INMO GO3’s rectangular lenses and softened corners give it the outline of conventional eyewear, although the frame has more substance than a pair of reading glasses. That’s a reasonable visual compromise, of course, given what it packs inside. The thicker brow provides room for the display hardware while giving the front a confident shape, rather than leaving its components looking like something awkwardly attached afterward.
The dark matte finish does much of the visual work. It gives the broad surfaces a quieter presence than glossy plastic would, while the small red accents around the hinges add a bit of personality. Thankfully, the color doesn’t spread across the frame. There’s enough contrast to make the details interesting without making the glasses look like equipment borrowed from a gaming setup.
The GO3 utilizes aluminum alloy and polyamide for the construction with a CNC-finished, fingerprint-resistant surface. It’s not an entirely metal object, which makes sense when you consider that the electronics also add their own weight to the equation. The frame and temples share a restrained finish instead of competing for attention through contrasting textures.
The slim temples measure around 8mm, keeping the side profile from becoming an oversized box. The curved ends retain the familiar outline of glasses, even with additional hardware inside. It isn’t dainty eyewear, admittedly, but the shape avoids the visor treatment that would make a business lunch feel like a technology demonstration.
The camera is integrated into the front rather than perched above it, and the controls follow the temples. These details help the INMO GO3 read as a somewhat fashionable object instead of gadgets sharing a frame. A supplied camera cover also provides a way to obscure the lens when recording isn’t appropriate, especially given the current conversations around smart glasses.
Ergonomics
At approximately 58 grams, the INMO GO3 has the weight of electronics to accommodate as well as the frame itself. Comfort depends on more than the number on the specification sheet. The relationship between the nose pads, temples, and ears matters as much. There’s a focus on those contact points, rather than relying on a lightweight label to explain away the fitting process.
Air-cushion nose pads support the front, while the temples offer 15 degrees of adaptive movement, at least on paper. That flexibility gives the frame room to accommodate differences in head shape. Naturally, there will be cases when the head shape just won’t fit, but INMO has tried to accommodate as many head sizes as possible.
Given we’re talking about glasses, prescription support is another important piece of that everyday equation. The GO3 uses an insert system, with INMO’s current lenses supporting nearsightedness and astigmatism, though not farsightedness. That won’t cover every prescription, but it gives supported wearers a way to combine vision correction and the display.
Operating the glasses doesn’t have to depend on talking to them. Temple touch controls and physical power and GO buttons provide alternatives, while the companion app handles setup and settings. When you’re around people or somewhere that requires a degree of silence, a discreet gesture is often preferable to a spoken command, and familiar controls help make the wearable format a little less foreign.
Performance
Two-Way Dialogue Translation – Read translations directly through the glasses, while the other person sees or hears your translated response on the phone.
The INMO GO3’s binocular green Micro-LED display uses optical waveguides, with a 640×480 resolution and a 30-degree field of view. Adjustable brightness is listed up to 1,500 nits, which is plenty even for the bright outdoors. That said, those specs clearly mark it as something more for text and guidance rather than a miniature cinema. Green lettering has a slightly retro character, but a translation or the next line of a speech doesn’t need a full-color backdrop to be useful.
Translation, of course, is the primary use case for these glasses, and the numbers are admittedly impressive. INMO lists 78 source languages and 98 target languages online, with subtitles appearing in view rather than on a phone held between speakers. Offline support covers nine languages on Android and 13 on iOS, and future updates promise even more. The phone still needs to stay paired to a phone, of course, but a missing internet connection needn’t end every supported conversation.
Built-In Teleprompter – Follow your script directly through the glasses.
For presentations, the teleprompter moves the script from a desk into the speaker’s field of view, allowing for a more natural-looking stage presence. There’s automatic voice-following advancement in 17 languages (including English, Mandarin, Cantonese, Japanese, Korean, German, French, Thai, Russian, Spanish, Portuguese, Polish, Arabic, Indonesian, Vietnamese, Dutch, and Italian), alongside manual scrolling from the temple. Other languages will be displayed, depending on the document uploaded by the user, but the pages for unsupported languages can’t be automatically turned by voice. Very few will be sitting close enough to realize you’re not exactly looking at them, but at least you won’t be spending half of the presentation staring down at your notes.
Photo Translation – Point the camera at written text and read its translation directly through the glasses.
The GO3 also offers features better used in meetings, such as recording, transcription, and AI summaries for later review. Walking and cycling directions, an AI assistant powered by ChatGPT and Gemini, and photo translation extend the same idea beyond work scenarios: put a useful answer nearby without making a phone screen the center of every activity.
Admittedly, many AI smart glasses offer similar features, but the INMO GO3’s killer feature is its interchangeable battery system. One 270mAh battery is installed in the glasses, with one spare included. Continuous use yields around 3 hours on a full charge, which is probably more than enough for most use cases. The 1,300mAh battery charging case offers three to four more charges, so you practically get a full day’s worth in total.
Where it gets interesting is how you can swap out the dead battery on the tip of the GO3 with the spare in the charging case. It’s quick and convenient, but not entirely seamless. The glasses will shut down when you pull out the battery, but plugging a fresh one in boots it up in just a few seconds. It does mean you have to briefly stop what you’re doing or make sure you’re not in the middle of something critical, but it’s better than waiting for minutes for the glasses to charge up.
Sustainability
The replaceable battery has a longer-term benefit beyond getting through a busy afternoon. An aging power cell doesn’t automatically have to take the entire pair of glasses out of service. INMO lists a replacement battery at $49, making that component a separate ownership expense. That’s a useful piece of product design: the part expected to wear with repeated charging doesn’t have to remain permanently sealed inside.
That doesn’t establish a complete sustainability story, and there’s no need to pretend otherwise. The reviewed specifications don’t establish recycled material content, comprehensive component repairability, or an end-of-life program. The more defensible advantage is the ability to keep the same frame in service when its battery needs replacing. Thoughtful care still matters, particularly for the lenses and hinges, but accessible power replacement is a concrete place to start.
Value
At $699, currently discounted to $509, the INMO GO3 asks for a commitment beyond casual curiosity. The standard package includes the glasses, installed battery, single spare, and battery charging case. That’s a coherent starting point, with the power system already accounted for. The value comes from using the display repeatedly, rather than paying for a collection of functions that remain untouched save for a few presentations or travels abroad.
The useful comparison is between priorities, rather than a contest over the longest feature list. Camera-and-audio glasses answer a different need from eyewear that puts text in view, while entertainment-focused displays serve another purpose again. For someone moving between multilingual conversations and presentations, the GO3’s combination is easier to justify. That it can also be your travel companion and AI assistant brings added value to the table, especially when you don’t look like a walking technology advertisement.
Verdict
The INMO GO3’s most appealing quality is how its design keeps returning to recognizable habits. Wear glasses, follow a conversation, glance at a script, and change a battery when necessary. The technology adds steps of its own, of course, but the physical form doesn’t ask for an entirely new routine. Its familiar outline and adaptable contact points give the translation and presentation tools a sensible place to live.
Travelers, presenters, and people working across languages have the clearest reasons to appreciate that combination. A paired phone remains part of most workflows, and battery changes belong between tasks, but neither qualification takes away the appeal of information placed closer to the conversation. There’s something refreshingly practical about glasses that leave room for ordinary interactions, even when a little green text is helping them along.
Your face is a power plant, and you’ve been running it for free your whole life. Every blink and jaw clench releases a tiny burst of mechanical energy that simply vanishes. A team at Northwestern University figured out how to catch it, using static electricity, the same stuff that makes a balloon stick to your hair. Their prototype glasses, GlassTENG, use that energy to run sensors tracking your pulse, blinks, and teeth clenching. As a feat of energy harvesting it’s fantastic, and I’d love to see it in everything from earbuds to shoe insoles.
Then the other shoe drops, because smart glasses are already the most side-eyed gadget around, with Meta’s Ray-Bans filming strangers in coffee shops and a battery that needs its case after a few hours serving as the only real limit. GlassTENG’s three sensors, built by Nivedita Arora’s VAK Embodied Systems Lab, draw just 4.1 microwatts combined, and the team wants to go fully battery-free next. That would remove the last speed bump on always-on face computers. Your pulse and jaw clenches are deeply personal data, and glasses like these could log them around the clock. Then again, if such glasses are coming anyway, I’d much rather they ran on blinks than on lithium-ion cells strapped to my head.
A Silicone Sandwich That Turns Blinks Into Voltage
The sensor is a two-layer sandwich of PDMS, a soft silicone, and FEP, a slick fluoropolymer from the Teflon family. When the layers press together and spring apart, one hogs electrons from the other, which is the balloon-and-hair trick in a lab coat. Silver electrodes, each 150 nanometers thick, collect the resulting voltage. Pulse is the faintest signal, around 50 to 100 millivolts, while blinks and eyebrow raises land at 200 to 500 millivolts. A hard jaw clench climbs to about 1.5 volts, which is a wide enough range for one thin stack to tell a heartbeat from a chomp.
The silicone is Sylgard 184, mixed 10 to 1, degassed, spin-coated to roughly 490 microns (about 0.02 inches), and left to cure overnight. The FEP gets blasted with oxygen plasma on both sides, which roughens the surface so more of it touches the silicone. The team started by etching one side, then found that doing both measurably boosted the signal. Bare silicone faces your skin while the charge-trading interface stays sealed inside, so skin oils can’t muck up the readings. It’s baking show energy, just with a vacuum chamber instead of an oven.
Three Sensors, Three Spots, and Your Head Doing the Clamping
One sensor sits on the nose bridge over the angular artery, where it reads pulse, forceful blinks, and eyebrow raises. A second hangs off a small arm near the temple, aimed at the superficial temporal artery to catch clenching, tapping, and chewing. The third is embedded in the temple arm above the ear, and here the design gets clever, because the natural clamp of the frame on your head supplies the contact pressure for free. Early 3D-printed nose pads gave patchy contact, so the team swapped in adjustable off-the-shelf pads from regular eyewear. Decades of optician ergonomics beat the custom part, which is a humbling result for any designer.
In a study with 20 people, half of them daily glasses wearers, a Random Forest classifier (a machine-learning model that takes votes from many decision trees) sorted six activities with 93.8% accuracy. Forceful blinks and teeth tapping both hit 99%. Heart rate landed within 1.82 beats per minute of a Polar H10 chest strap, measured on 10 seated volunteers at rest. Talking was the weak spot at 55%, and the system mistook it for eating 37% of the time, since both work the same jaw muscle. For now, your glasses might assume you’re mid-sandwich when you’re just mid-rant, and honestly, I know people like that.
4.1 Microwatts: The Number Every Battery Spec Should Fear
Those 4.1 microwatts cover the sensing front-end, the circuitry that cleans up the sensor signal, and they look tiny next to the alternatives. The paper pegs optical pulse sensors (the glowing green lights on your smartwatch) at 1 to 10 milliwatts, and gel-based muscle sensors at 10 to 160 milliwatts. On a 100 mAh battery, the authors calculate that the GlassTENG front-end would cost less than half a minute of runtime, where an optical sensor would burn through hours. The prototype still uses a small battery for its microcontroller and Bluetooth, and fully battery-free operation is listed as future work. Even so, shrinking the sensing bill to almost nothing is what lets a frame stay a frame.
Ray-Ban Meta Gen 3 starts at $449 and rates nine hours per charge, while the Meta Ray-Ban Display runs $799, and that charging case remains the main limit on how long those glasses can watch the world. GlassTENG has no price or release date, so nobody is buying it this holiday season. I’d happily see self-powered sensing in earbuds, insoles, and medical patches. Glasses are the tricky one, because the cleverer the sensor gets, the fewer excuses a company has to leave it off. Still, if face computers are coming regardless, I’ll take the pair powered by my own twitchy eyelids over the one with a lithium cell parked next to my temple.
Your phone focuses by firing an invisible laser pulse at whatever you’re aiming it at, timing the bounce, and telling a tiny motor to move some glass. The whole loop finishes in a few hundredths of a second and nobody has thought about it since roughly 2017. VIVIFoCAL has taken that identical hardware recipe, a time of flight sensor, a microcontroller and an actuator, and bolted it onto a pair of glasses pointed at the world instead of at your brunch. The S1 measures how far away the thing you’re looking at is, works out the optical power your eyes need, and mechanically shifts the lenses into position in under 0.1 seconds. It’s autofocus, except the sensor is on your face.
Dr. Zhao, who earned his doctorate at a world-leading university and previously ran an optical R&D laboratory at a major optics company, built VIVIFoCAL around a piece of physics that has not yet been widely adopted by the general public. The S1 uses Alvarez lenses, two complementary freeform elements that change optical power when one slides sideways across the other. Nobel laureate Luis Alvarez patented the principle, and it was then stranded for decades because somebody had to do the sliding. A motor does it now. The result covers 8 inches to infinity in a 40 gram frame, and it launches with VIP pricing from $289.
A laser, a motor, and the 1967 patent working in the background
Three sensors do the work rather than one. A time of flight laser reads distance, a G-sensor tracks head posture, and an infrared wear detection sensor tells the glasses whether they’re on a face at all, which is how the battery survives being pushed up onto your head mid-conversation. The microcontroller sits between them, converting a distance reading into a lens position and commanding the motor in a single pass. The lenses simply change optical power to match whatever distance you’re looking at, the same job your eyes handle on their own before presbyopia kicks in. VIVIFoCAL calls that loop Instant Focus, and the same time of flight hardware we’ve watched migrate into phones, robot vacuums and door locks is what makes it affordable in eyewear.
Fitting a moving lens assembly, a rangefinder, a motion sensor, a microcontroller, a motor and a battery into something that still reads as eyewear is the harder half of this product. VIVIFoCAL has pushed the electronics into the brow bar and the temple arms, keeping the optical stack shallow enough that the frame sits on a face instead of announcing itself as hardware. The 160.5 x 160 x 43.5mm envelope is ordinary spectacle territory, which is the entire argument. Every packaging decision is downstream of one goal, helping the wearer see clearly across distances without thinking about the machine doing it.
Progressive lenses ask you to tilt your chin… this doesn’t
Presbyopia is projected to affect 2.1 billion people by 2030, and the standard answer for most of them is a progressive lens with three prescriptions blended into one lens, near at the bottom, distance at the top, intermediate smeared between. Finding the right part of the glass means tilting your chin, and the tradeoff is the narrow tunnel vision that progressive wearers describe, with softness creeping in toward the edges. VIVIFoCAL calls its answer Full-Lens Clarity, where the Alvarez lenses deliver one consistent optical power across the whole lens at every setting instead of splitting it into zones. There is nothing to hunt for and less peripheral distortion to work around. I’ve watched that chin-tilt dance play out for years, so the appeal is obvious.
Progressive glasses are generally built around everyday reading tasks, and for closer or more detailed work plenty of wearers still reach for a second pair or a magnifier. S1’s focusing range starts at 8 inches, which brings fine detail inside the same lens handling everything else. VIVIFoCAL demoed the glasses at WonderFest 2026 against a 1/35 scale miniature, the sort of precision hobby work that has kept optical visors and loupes in business for a century, and the testers who work with their hands responded the way you’d expect. One early tester shared that using S1 in a data center was a productivity gain and a huge plus, because he could walk past equipment and read tiny serial numbers without interrupting his workflow to take out extra readers, switch to other glasses, or use additional visual aids. He no longer carries multiple pairs when he leaves the house.
Forty grams, three nose pad sizes, and all-day power
VIVIFoCAL designed around the fact that head sizes and nose bridge heights vary far more than eyewear brands usually admit, which is why S1 ships with flexible spring hinges and three sizes of interchangeable nose pads to adapt across face shapes. The frame lands at 40 grams bare and 50 with the magnetic front clip, built on TR90 temples, the same material that has quietly taken over lightweight frames and wearable arms across the industry. Those numbers matter because forgetting you’re wearing them is the whole point of automating focus in the first place. A 250mAh battery holds up through 8 hours of constant refocusing and refills over USB-C in about an hour, with normal use stretching to a full day. Glasses that can run flat is still a new idea to make peace with.
A separate pair of lenses attaches behind the Alvarez elements, so one pair carries your prescription to see near and far. Magnetic polarized sunglass lenses snap onto the front for outdoor use with adaptive focus still running underneath. The polycarbonate lenses carry anti-reflective and anti-smudge coatings, transmit more than 90 percent of light, and sit inside a field of view above 110 degrees. The app adds a ±0.5D fine-tuning range on top of the automatic correction, which is how the glasses absorb the slow drift of a presbyopic prescription instead of being replaced. Presbyopia correction tops out at 3.5D, so the deepest cases fall outside what S1 can currently handle.
The bet VIVIFoCAL is making on moving glass
The company isn’t chasing this idea alone. Other teams are working on adaptive focus through liquid crystal lenses or eye tracking instead of a mechanical shift, and the category is young enough that the approaches are still diverging. VIVIFoCAL is betting on the refractive route, real glass moving to change optical power rather than a pixelated layer simulating it, and that bet buys the two things that matter most in eyewear you keep on your face all day. S1 holds above 90 percent light transmittance and a field of view past 110 degrees, which is why the image through it behaves like a lens instead of a screen.
Alvarez lenses have been a lab curiosity since 1967 for one reason, which is that the sliding had to be automated by something small enough to live inside a temple arm. Sensors, motors and microcontrollers have finally shrunk far enough to make that trivial, which makes S1 a triumph of packaging, and packaging is where most wearables actually get decided. Autofocus earned its invisibility in cameras by working so fast nobody noticed it, and 0.1 seconds across 8 inches to infinity puts the same disappearing act in front of your eyes. S1 ships with a 1-year warranty, and a refundable $10 deposit locks in VIP pricing at $289 ahead of the official launch, with either the prescription lens service or the sunglass lens bundle included depending on which one you need. Sixty years is a long time for a good idea to wait for its motor.
