What is an Amsler grid?

If you have dry AMD, you’ll normally be monitored by your optometrist. They may ask you to return for regular appointments so they can monitor any changes to your AMD and to your sight.

Between your appointments, you may be advised to monitor your vision at home regularly by closing one eye at a time and looking at window/ door frames or tiles to see if there is any distortion. Some optometrists may provide you with a paper‑based test called an Amsler grid along with instructions to help you monitor your vision at home. An Amsler grid is made up of horizontal and vertical lines with a dot in the centre of the grid that you use as a focal point when checking for any distortion. This test is done while wearing your reading glasses (ideally not varifocal glasses).

If at any time between appointments, you feel like your vision has deteriorated, you should let your optometrist know straight away.

You can order an Amsler grid from RNIB's online shop.
