Workouts

Screen strain builds up quietly. Do the full workout, or pick one — each takes under a minute.

Getting ready · Sound

Can you hear me?

Iris uses a spoken voice to guide you, with everything also written on screen. You should be hearing it right now.

If you continue silently, all instructions stay visible as text on screen.

Getting ready · Microphone

Now, can I hear you?

You'll answer out loud during the tests. Allow microphone access when your browser asks, then say “hello” to check it's working.

Waiting for your voice…

Skip — I'll tap answers instead

Getting ready · Set-up

How far back are you?

No camera? No problem. Just pick roughly how far back you'll be — big steps are about a metre each — and press continue.

Getting ready · Distance

Hold still a moment

Iris sizes the letters to exactly where you are. Look toward the camera and keep still for a few seconds — it locks on by itself, nothing to press. Nothing is recorded or sent — the picture never leaves this device.

The eye scan

Look right at the camera

About an arm's length away, both eyes open, glasses off if you can. Hold still for a few seconds.

Eye dominance

Which eye do you really see with?

Hold both hands out at arm's length and form a small gap between your thumbs and fingers. Look through the gap with both eyes open and line it up on something across the room. Now, without moving your hands, close your left eye only.

Convergence

Can your eyes team up close?

Hold a pen, pencil or your fingertip at arm's length. Focus on the very tip with both eyes, then slowly bring it toward your nose — keeping it single and in focus for as long as you can.

Both eyes
Rapid number naming
Read every number aloud, left to right, top to bottom — as fast as you can, without skipping any.

For opticians

Patients finish a check here — then choose where to book

Iris guides people through a full at-home eye screening. When something's worth a professional look, they're shown nearby practices and pick one to book with — that's the moment your practice should be on the list.

Founding practices get listed free. No integration needed to start — just your practice name, town and booking link. When online booking slots come later, founding practices keep priority placement.
Apply to get listed

Applications are reviewed by a human. Listing is free while Iris is in its founding period.

Watching over your eyes

Iris keeps an eye on how close you're sitting, how often you blink, and when you're due a screen break. Pop out the mini monitor and it keeps watching while you work in other tabs and apps.

Turn the voice off with the speaker button and Guard nudges you with quiet system notifications instead — perfect for leaving it running in a background tab while you work.

Book In-Person Test

Iris is for curiosity, not diagnosis — nothing here replaces a real eye exam, and nothing you did leaves this device.
