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. Now the chloroid is basically the layer below the sclera. So if the sclero is this white portion, the layer below that is our chloroid. And the chloroid actually contains the vascular portion of the eye, the portion that contains our connective tissue.
