An Amsler grid is an easy-to-use self-monitoring tool used to detect changes in your vision which may include symptoms like distortion (straight lines appearing wavy), blurred patches or dark patches.

How to use an Amsler Grid

1. If you use reading glasses, you should wear them when using an Amsler grid.
2. Hold the grid at your normal reading distance, that’s usually about 30cm from your face, in a well-lit room.
3. Cover one eye with your hand and focus on the centre dot with your uncovered eye.
4. Repeat with the other eye.
5. If there are any changes or symptoms, contact an eye health professional.
