For example, no human can with reasonable accuracy, visually determine the speed of an approaching train in the evening as they could during the day.[12][14][15] The choroid contains blood vessels that supply the retinal cells with necessary oxygen and remove the waste products of respiration. In some animals, the retina contains a reflective layer (the tapetum lucidum) which increases the amount of light each photosensitive cell perceives, allowing the animal to see better under low light conditions. The secondary colors can be further complimented
[14] The cornea and lens help to converge light rays to focus onto the retina. Water in the eye can measure relative speed with high accuracy, however under movement relative speed is highly distorted. The retina contains two forms of photosensitive cells important to vision—rods and cones. As for the optic nerve, once it is damaged it cannot be fixed. This light causes chemical changes in the photosensitive
