Although we highly advise seeking regular tests by an optometrist, you can test your eyes yourself with an Amsler grid in between your optical check-ups.
- Put your reading glasses on and cover/close one eye.
- Hold the Amsler grid at reading distance. You can print it out on a piece of card.
- Keep your eye fixated on the small black dot in the centre.
- Keep your gaze completely still and fixed on the black dot and watch to see if any of the grid lines are missing or distorted.
- Mark these abnormalities on the chart with a pencil/pen.
- Make sure that you test each eye separately.
Always keep the Amsler grid the same distance from your eye each time you do a test and report to your optometrist if you notice any changes.
An eye without wet AMD will see the lines on an Amsler grid as straight. An eye that has wet AMD will view the lines on an Amsler grid as being curved, or obstructed by white, grey or black areas. This is caused by the build up of fluid within or under the retina. This forms a blister, making the straight lines on the Amsler grid look curved. If the fluid interferes with the retinal function enough, blind spots towards the central area of the visual field can appear.
