Colour-Blindness Test

Color-Blindness Test is a simple, ad-free way to check your colour vision using the classic Ishihara plate method. Colour blindness is the inability to distinguish between certain colours. It results from a deficiency of colour-sensitive pigment in the cone cells of the retina. The most common form is red-green colour blindness, where red and green are perceived as the same colour. Roughly 8% of men and 0.5% of women are affected, most of them from birth. FEATURES • 50 high-resolution Ishihara
