Light enters the eye through the transparent cornea and passes through the pupil, the diameter of which is determined by the iris. It then passes through the lens of the eye which bends the light (refraction) to focus it on the back of the retina. The image projected on the retina stimulates receptors that transmits >> Read More ...
The human eye consists of the eyeball, optic nerve, orbit and appendages (eyelids, extraocular muscles and lacrimal glands). While the eyeball is the actual sensory organ, the other parts of of the eye are equally important in maintaining the health and function of the eye as a whole.
