The cornea is the front part of the eye. It is the clear transparent section of the eye. The cornea covers the iris, pupil, and the eye chamber. It is a special form of tissue. The cornea is clear and has no blood vessels. It has nerves, but with no myelin sheaths on them.
The cornea, with the lens, refracts light. The cornea and the lens bend light so the image strikes the retina. The cornea does about two-thirds of this refraction.
