Amsler grid test
A simple, one-minute check you can do at home to spot early changes in your central vision — particularly useful if you're managing or at risk of macular degeneration (AMD).
How to use it
- If you normally wear reading glasses, put them on.
- Hold this page about 30–40cm from your face, in good light.
- Cover one eye, and look directly at the black dot in the centre of the grid.
- Without moving your eye, notice whether any of the lines look wavy, blurred, or missing.
- Repeat with the other eye covered.
The grid
When printed, this grid measures 10cm × 10cm — the standard size for this test.
