The human eyes are responsible for ninety percent of all information received on the outside environment. The eyes transmit its information to the brain by the use of photoreceptors and phototaxis. Photoreceptors are pigment molecules embedded in the membrane of receptor cells. The receptor cells are the phototaxis, a name for any sensory neuron that receives light, absorbs light(energy) and raises the threshold and produces a reaction to the axons leading to the brain. The human eye can be divided into three structures, the outer which consists of the sclera(the white fluid) and the anterior extension or bulge that is the cornea.
