Amblyopia (Lazy Eye) Screening

← All tests

Part 1 — Compare your two eyes

Amblyopia usually shows up as one eye seeing much worse than the other (two or more chart lines of difference). You'll take a short acuity test twice — first with your left eye covered, then with your right eye covered. Sit at your calibrated distance (—).

💡 For a glasses-free version of this test, try the VR mode — a headset can show each eye a different image, so no covering is needed.

Part 2 — Stereo vision (optional, needs red-cyan 3D glasses)

Amblyopia often impairs depth perception. If you have red-cyan anaglyph 3D glasses (red lens on the LEFT eye), put them on: a square will float above the noise in one corner — click the corner where you see it. Without glasses, skip this part.
