ISHIHARI COLOUR VISION TEST CHARTS

Back To Product & Technical Info Index

These charts are a basic colour vision test and assume correct setting up and calibration of your computer monitor and that it it is in good working order. They are in no way a definitive test but for simple guidance only and for the most common (Red/Green) deficiency.

Note the numbers in each of the frames below then go to the bottom of the page for the check list.

The background of this page has been deliberately left neutral to facilitate the test. If you think you have a colour vision problem please consult your Optician.

A Simple Test
