Now, the next portion we're going to discuss is the cornea. The cornea is the outside portion found in the front of the eye. And unlike the sclera, the cornea is clear, it's transparent, and that means it absorbs very little of the light and it allows most of the light to actually pass through. Now, the cornea contains an index of refraction of about 1.4, which is much higher than the index of a fraction of air. And because of this relatively large difference between the index of refraction of the air and the cornea, most of the bending of light in the eye actually takes place on an inside arneum. Now, the next portion I'd like to discuss is the chloroid.
