endothelium
Outermost tunic made up of of Fibrous connective tissue
Sclera
Composed of blood vessels and lies between the sclera and retina. It provides blood supply for the outer cells of the retina. Regulates the temperature
Choroid
Innermost layer of the eye
Visual pathway to the brain
Converts light entering the eye via nerve impulses
Retina
Photoreceptors of the retina. Night vision, no color vision found in periphery
Rods
Photoreceptors of the retina. Day vision, color vision. Ice cream in the sun
Cones
Transparent avascular tissue 40-44.00D
The cornea
Refractive index of cornea
