Point your camera, follow the friendly on-screen guide, and OcuScan AI checks redness, blink health and pupil symmetry — then four quick vision games screen your sharpness, color vision and more. Everything runs on your device.
Do them in any order — the report assembles itself as you go. Best in a bright room, about an arm's length from the screen.
Fully automatic — position your face in the oval and the AI does the rest. Checks redness, pupils, blinking & dryness signals.
A letter "E" points up, down, left or right — tap the arrow that matches. It shrinks while you win.
Spot the hidden number in the colorful dot circles — classic Ishihara-style screening, freshly generated each time.
Stare at the fan — if some lines look darker than others, that's a classic astigmatism signal.
Stare at the dot, judge the grid with your side vision — screens your central (macular) vision.
Letters fade step by step — how faint can you still read? Catches issues acuity tests miss.
Find the smallest paragraph you can read at arm's length — screens for presbyopia (reading power).
Combines your test results into an estimated prescription — SPH, CYL & axis, reading ADD — per eye.
One clear, printable report with a health score, per-test results and friendly next-step advice.
Small tools that keep your eyes happy between screenings.
Match an on-screen card to a real bank card once — every test size becomes accurate for your screen.
Every 20 minutes, look 20 feet away for 20 seconds — the classic anti-strain rule. I'll keep time.
Screening raised a flag, or it's been over a year? Find optometrists near you in one tap.
Save each screening to your device and watch your scores over time. Stored locally, never uploaded.
No buttons needed — just fit your face inside the oval and follow the coach. When you're positioned well, a countdown starts and the scan runs by itself. Bright, even lighting gives the best results.
Sit about 1 metre from the screen. Each eye is tested separately — cover the other with your palm. Tap the arrow matching the direction the E points (keyboard arrows work too). For an accurate Eye Power estimate, test without glasses. Tip: calibrate your screen first for best precision.
A number hides in each dot circle. Tap what you see — or "Nothing" if no number appears. Use normal screen brightness and switch off night-mode color filters.
Cover one eye and stare at the centre. With astigmatism, some lines often look darker or sharper than others. Keep glasses/contacts on if you normally wear them.
Do all the lines look equally dark and sharp?
Hold any standard bank / ID card against the screen and drag the slider until the blue card is exactly the same width. This tells the app your screen's true size, making every test medically sized.

Hold your usual reading distance (~40 cm), wear your normal glasses if you use them for distance (not readers). Both eyes open. Read each paragraph — tap the smallest one you can read comfortably.
A letter appears fainter and fainter. Tap the letter you see — or "Can't see". Normal screen brightness, no night-mode filters. Both eyes open.
Your test results, translated into an estimated prescription — sphere (SPH), cylinder signal (CYL) with axis, and reading addition (ADD). For real numbers only a professional refraction will do; this gives you a strong starting indication. Acuity must be done without glasses.
Every saved screening lives here — on your device only. Save from the Report page after testing.
Hold reading distance (~35 cm). Cover one eye, stare only at the centre dot, and notice the grid with your side vision. Tick anything unusual below.
