Color Blindness Test

The software is is simple in concept to find the achromatchart with worsteds for testing color blindness.Colour blindness is basically a malfunctioning of the retina of the eye, which is responsible for the conversion of light energy into electrical energy, which is thereafter transferred to the brain in the form of signals. The conversion is carried out by two types of photoreceptor cells within the retina: cones, and rods. Disturbances or disorders in colour perception will occur when the amount of pigment present per cone is reduced, or absent.
