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.

The cornea is the most powerful structure focusing light entering the eye. 2  retina The retina is the innermost layer of the eye.
