Eye tests for self-assessment
Five tests with stimuli calibrated to the real size of your screen, for information only. They are not a screening, a diagnosis or a medical opinion and they do not replace an eye examination: to find out how your eyes are, you need an eye doctor.
Prepare the room
A well-lit room, screen brightness at maximum, and wear the glasses you normally use.
Calibrate the screen
Where needed, a credit card held against the screen gives us the real dimensions: the stimuli will be the right size.
One eye at a time
Almost all the tests examine one eye at a time: cover the other with the palm of your hand, without pressing.
Astigmatism Test
Fan dial: say whether some lines look blacker or sharper than the others, a possible sign of astigmatism.
Start the testColour Test
Five Ishihara plates (plus a practice one) to test your ability to tell colours apart.
Start the testVisual Acuity Test
Landolt C optotypes calibrated on a logMAR scale: an indicative estimate of how sharp your eyesight is, for each eye.
Start the testContrast Sensitivity Test
Stimuli of decreasing contrast in constant logarithmic steps: an indicative estimate of your contrast sensitivity, for each eye.

Only an eye examination can confirm or rule out an eye condition. Find the prevention centre nearest to you and book a check-up.
