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.
White part of the eye, thick, tough, protects the eye. The transparent potion of it is known as the cornea. Retina. First internal layer of the eye, contains photoreceptors (rod and cone cells) Rod Cell. Photoreceptor: Less Abundant. More common in the periphery of the retina.
