Online Eye Tests

Three quick screening tests you can do at home: Amsler grid (macula), astigmatism dial and colour vision. These tests do not replace an eye examination; if you notice anything unusual, see an eye doctor.

Important: Screen size, brightness and distance affect the results. These tests are for information only and do not diagnose. Sudden vision loss, flashes of light or a curtain in your vision are emergencies — call 112.

1. Amsler grid (macula / yellow spot)

Hold the screen about 35 cm away. If you wear reading glasses, keep them on. Cover one eye and look only at the dot in the centre. Then repeat for the other eye.

While looking at the centre dot, did you see wavy or bent lines, blurred or missing areas, or squares of different sizes?

2. Astigmatism dial

Stand about 1 metre from the screen. Wear your glasses if you have them. Cover one eye and look at the centre of the dial, then repeat for the other eye.

Do some lines look darker, sharper or thicker than the others?

3. Colour vision

Look at each plate from a normal reading distance and choose the number you see. If you see no number, choose "None".
