CN II - Colour Vision

Color vision is the ability of an organism to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit or transmit. Eye specialists perform colour vision tests to get an idea of one’s color efficiency or deficiency. Virtual activity tests the color perception for red-green color deficiencies using Ishihara plate by listening to the patient’s response.
