Central Vision Screening

AMSLER
GRID
TEST

A 10×10 line grid with a center dot. You stare at the dot and report what you see. Each eye tested separately. Takes about 2 minutes total.

What this test screens for

The Amsler grid detects distortions in your central 20 degrees of vision — the area served by the macula. Distortions can be associated with age-related macular degeneration, macular edema, epiretinal membrane, and other central retinal conditions. This tool screens, it does not diagnose.

How to take the test

If you wear reading glasses or progressive lenses, keep them on
This test is meant to be taken at normal reading distance (~30–40cm / 12–16 inches)
Cover one eye with your palm — not a lens
You will test right eye first, then left. A cover reminder appears before each eye.
Keep your open eye fixed on the center red dot — do not let it wander
Use your peripheral vision to judge the grid. If you move your eye, the test is less accurate.
If you see distortion, tap the area on the grid where it appears
Then answer the questions below the grid about what you observe.

Results Disclaimer
These results are screening observations only, not a diagnosis. The Amsler grid is a simple self-administered tool. Many non-pathological factors including screen pixel structure, lighting, and normal optical variation can produce apparent distortions. If you reported distortions — especially asymmetric distortions between eyes — consult a licensed optometrist or ophthalmologist promptly. Results are processed locally and never transmitted.
