Contrast sensitivity check

Contrast sensitivity is the ability to see an object against its background — a different aspect of vision from ordinary visual acuity.

Important: Screen brightness, glare, viewing distance and display quality affect the result. This gives an indication only and cannot replace an eye examination.

Before you start

Set the display to a comfortable, stable brightness and turn off colour filters.
Avoid glare or bright light falling directly on the screen.
Wear your usual glasses or contact lenses for this viewing distance.
Test each eye separately by gently covering the other eye without pressing on it.
