More Information About Color Blindness

Normal vision means you have normal photopigments, or color-detecting molecules, that allow you to see a full array of colors. Color blindness or deficiency, means your photopigments are abnormal causing your color perception to be limited and inaccurate.

There are 3 main types of colorblindness; take the test to find out if you could be colorblind. If you believe you could have color vision deficiency, consult with your eye care professional.

What’s this test based on?

EyeQue uses the industry standard Ishihara test to measure color perception and screen color deficiencies. The process consists of colored plates, aka Ishihara plates, which contain a number among dots, randomized in size and color. Since its creation by Dr. Shinobu Ishihara in 1917 it remains the most accurate color perception for red-green color deficiencies.
