Human color perception apparatus (optic nerve and brain) | |||||
When the light reflected off an object enters the human eye, it reacts with the photoreceptors in the retina, and the signals are sent to the brain. Some photoreceptors are sensitive to light and shade, and others to red, green, and blue wavelengths. When these signals are received, the brain perceives color. Color blindness or anomalous trichromatism occurs when the function of these nerves is impaired. | |||||
Some animals cannot see in the dark, while others see very well under these conditions. Dogs and cats do not see colors. All of these variations are determined by the function of the optic nerves. | |||||
