The following page explains basic anatomy of the human eye and highlights some structures in particular and how they relate to cataracts and cataract surgery. Some of this light enters the eye through an opening called the pupil pyoo pul. Nerve signals that contain visual information are transmitted through the optic nerve to the brain.

The iris helps regulate the amount of light that enters the eye. Basic eye anatomy. The retina receives light and sends electrical impulses to the brain that result in sight.

Although the eye is small relative to most organs in the human body it has many distinct anatomical parts all of which contribute to the production of normal vision in one way or another.
