Look at it.
That's the whole interface.
Health glasses that read your body at eye level and act on what they find: heart rate, blood oxygen, sleep and daylight, from a sensor in the temple. No wrist. No dashboard. No phone in your hand.
Putting a screen on your face
is the easy part.
Reading your body from it is not.
Every other frame on the market is a display looking out. Theora is a sensor looking in, which is a harder problem: holding a clean pulse against bone, all day, on a face that moves and sweats and talks. That is not a first attempt. Two decades of wearable optics and head-mounted hardware sit on this team, breadboard through production tooling, and our hardware lead has already taken AR headsets off a bench and into a manufactured product once. Our optics advisor holds an endowed chair at one of the oldest optics institutes in the country, and the near-infrared retinal camera comes out of that lab. The frames themselves are built by a manufacturer who has been making waveguide eyewear at volume for years, not in a garage.
The one thing we will not claim is that the frame is finished. It ships in 2026. What is already real is the team behind it and the hundred people wearing an earlier build every day while we get there.
You wake up already
knowing.
Play it. The panel follows the film, every reading that appears in his lens, and why it appeared at all. Jump between moments with the markers.
And this is the night it scored.
The whole eight hours, from a sensor that never left your face. Drag across it.
It sees what you see.
It hears what you hear.
Not an assistant you summon. Dual cameras at eye level, a four-mic array, and a waveguide that answers back into one eye, running while you go about your day and feeding one agent that already knows what your week looks like. The recording is not the point. The point is that you stop having to be the one who remembers.
What you were looking at
The shelf you were standing in front of when you said you were out of it. The label on the bottle. The receipt you never photographed, because you did not have to.
What you were told
The date somebody gave you in a corridor. The name of the person who introduced themselves while your hands were full. The address said once, quickly, in a car.
Where it happened
Context attached to a place rather than a time, so a reminder can surface at the door of the shop instead of at nine on a Tuesday when it is no use to anyone.
And then it acts on it
This is where FERAL takes over: the calendar entry you did not type, the note filed against the right person, the message drafted before you have sat down.
What it sees and hears is handled by FERAL on your own hardware. It is not uploaded to train a model and it is not sold. FERAL is open source under Apache 2.0, public on GitHub, so that is a claim you can read rather than one you have to believe.
It does not show you numbers.
It does something about them.
Five moments from a single Tuesday. Every glowing point is something Theora noticed on its own, click one to see what appeared in the lens, and what it did about it.
Playing by itself. Move your cursor across the frame to take over, hover to find a point, click to open it.
Nothing selected yet. Click one of the glowing points on the left to see what Theora put in front of your eye, and the action it took without being asked.
The glasses are the sensor.
FERAL is what makes them
worth wearing.
Without it these are a camera and a pulse reader. FERAL is the private, local-first agent that turns those signals into something that acts, and the longer you wear the glasses, the better it gets. Step around the loop.
It runs on your phone, not ours
Local-first by design. Your body data and everything the agent remembers stay on your own devices. Nothing is uploaded by default, nothing is sold, and there is no advertising model on the other end of it.
You can read the code
FERAL is open source under Apache 2.0, public on GitHub. A privacy promise you can check is worth more than one you have to believe.
Every action is gated by policy
It can suggest moving your calendar, ordering your regular, or calling someone. It never does any of it without your say-so, and you set the boundaries once rather than approving forever.
Every sensor is a node
New capabilities register over one protocol instead of forcing a rebuild. That is how the retina and blood-pressure work reaches you later without replacing what you already own.
Stand in a real street
and look for yourself.
A full 360° viewer, right here. Drag to turn your head, and every readout stays pinned to the thing that earned it. Press Full screen to fill the display.
A plaza in San Francisco. Drag to turn your head. Every readout is pinned to a real thing in it, and slides out of view when you look away, exactly as it would through the lens.
Click any point below and it turns to face it. Or drag to look around and click the rings yourself.
Look around and click one of the glowing points. Each one is something Theora noticed by itself, with the reason it appeared and what FERAL wrote down or pulled back out.
Every readout is anchored to something
A step nudge belongs on a staircase. A decibel reading belongs on the thing making the noise. A meeting belongs on the door you are walking toward. Floating body data over a random building is the tell that a demo was faked, so nothing here appears anywhere it could not be earned by what is actually in front of you.
What to shoot for the real thing
One 360° still per location, taken at eye height with any consumer 360 camera, plus a note of what is worth pointing at in each. The HUD is drawn in the browser, so the readouts can change without a reshoot, but the anchor points have to be chosen by someone who looked at the frame.
He was working.
It told him to call his son.
A father at his desk. A reading that did not look right. One line in his vision at the moment it mattered, and he did not open an app, check a dashboard, or go looking for it.

Nothing here needed a phone
The prompt arrived where he was already looking, and acting on it was two words. That is the difference between a device that reports and one that does something.
This is what agentic actually means
Not a chatbot on your face. Something that has watched long enough to know what normal looks like for the people you care about, notices when it slips, and does the one useful thing about it.

The things people ask before reserving.
Something we have not covered? Email info@theora.io.
What is Theora?
Theora is a pair of agentic health glasses. They look like everyday eyewear, sense at eye level, and run on FERAL, a private local-first AI hub. Rather than showing you a dashboard, they notice small changes and act on them, hands-free.
How is this different from a smartwatch or fitness band?
A wristband tracks and reports; you go looking for the data. Theora sits at eye level, so it also sees and hears your context, and FERAL acts on it in the moment without being prompted. It orchestrates your glasses, phone and the devices around you rather than filling in another chart.
What does Theora Lite cost?
Theora Lite is $499 at the early-bird price, down from $599, plus $15 per month once it ships. A refundable $10 deposit locks that price in and is credited toward the purchase, so the balance at checkout is $489.
Is the $10 deposit refundable?
Yes. The $10 deposit is fully refundable at any time before your unit ships, and it is credited toward your $499 early-bird price if you go ahead.
Does my health data go to the cloud?
No, not by default. FERAL is local-first and open-source under Apache-2.0. Your body data and the agent's memory stay on your own devices, and they are never sold or harvested into an ad model.
Has anyone actually worn Theora?
Yes. Around 100 people wear a v1 unit daily, and most of them paid for it. That build is not the one you are reserving: it is an earlier, lesser version we use to learn from. Wear time, comfort, and which readouts people glance at rather than ignore all feed into the production frame that ships to the early-bird cohort.
What sensors are in the frame?
The frame ships with a 6-axis IMU, dual front cameras, four microphones and a waveguide HUD, all around 50 grams. Temple wellness modules add heart rate, SpO₂, skin temperature and UV sensing, with blink and gaze joining the suite over time. Full detail is on the technology page.
Is Theora a medical device?
No. Theora is a general wellness product and is not intended to diagnose, treat, cure or prevent any disease. Its metrics and insights are for general wellness and informational purposes only.
Can I change the lenses?
Yes. Theora Lite ships as everyday eyewear with swappable sun and anti-blue-light lenses, and comes in two finishes, graphite black and sand beige.

Most of them paid for it. That unit is not what you are reserving: it is a lesser v1 we use to learn from, and it is a generation behind the production frame. What it tells us about wear time, comfort, and which readouts people actually glance at goes straight into the one that ships.
