Pole of the Eye Anterior

The pole of the eye is the narrowest, outer part of the eyeball. The pole is located between the cornea, which is the outer layer of the eye, and the iris, which determines the color of a person's eyes. The pole does not have yellow or green pigment like other parts of the rainbow, so it appears transparent. In the front part of the eye, the iris is very dense and because of this it can be somewhat difficult to determine the boundary between it and the previous layer - the sclera, which contains the sclera and the nervous system of the eye.

Anterior to the iris lies the cornea. It consists of two layers: epithelium and endothelium. The cornea is transparent and protects the front of the eye from damage.

The easiest way to see the iris is to look into the eyes of your own reflection in the mirror. It may be noticeable
