High Contrast Text Size



by Dr. Cesar A. Perez, Jr.

The eye is a hollow ball-like organ, roughly the size of a lanzones fruit. In front are the transparent cornea and the white sclera; inside are the iris, lens and the retina. At the back is the optic nerve. Vision passes from the cornea, through the clear aqueous fluid, through the center of the iris called the pupil, through the crystalline lens, through the clear vitreous gel, and stops at the retina. Impulses are then transmitted from the retina to the brain via the optic nerve.
