The Cornea. The cornea represents the strongest part of the refracting power of the eye, providing about 80% of the power of the system. The index of refraction of the cornea is about 1.376. Rays pass from the cornea into the watery fluid known as the aqueous humor which has an index of refraction of about 1.336, so most of the refraction is at the cornea-air interface.
Eyeball. The main part of the eye is the eyeball (also known as the globe), which is mostly filled with a jelly-like material called vitreous humor. The eyeball has 3 main layers: the sclera, the uvea, and the retina. Sclera: The sclera is the tough, white covering over most of the outside of the eyeball.rimary intraocular lymphoma (lymphoma of the eye). Lymphoma is a type of cancer that starts in immune system cells called lymphocytes. Most lymphomas start in lymph nodes, which are bean-sized collections of immune system cells scattered throughout the body.
