It is composed of millions of visual cells and it is connected by the optic nerve to the brain.
Basic anatomy of the eye. The retina receives light and sends electrical impulses to the brain that result in sight. 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. There are many parts of the eye.
The cornea is shaped like a dome and bends light to help the eye focus. Muscular structure of the eye that widens and constricts the pupil in correlation with the intensity of light passing through lens suspended behind the pupil controlled by ciliary muscles and focuses light onto the retina. The eye is surrounded by the orbital bones and is cushioned by pads of fat within the orbital socket.
The eye is approximately 1 inch 254 cm wide 1 inch deep and 09 inches 23 cm tall. The crystal clear dome that covers the front of the eye. The anatomy of the eye includes the cornea pupil lens sclera conjunctiva and more.
A small area in the retina that contains special light sensitive cells. Extraocular muscles help move the eye in different directions. Next light passes through the lens a clear inner part of the eye.

A closer look at the parts of the eye by liz segre when surveyed about the five senses sight hearing taste smell and touch people consistently report that their eyesight is the mode of perception they value and fear losing most. Basic eye anatomy.
Although small in size the eye is a very complex organ. Nerve signals that contain visual information are transmitted through the optic nerve to the brain. Anatomy of the eye.

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. A thin multi layered membrane which lines the inside back two thirds of the eye. The lens works together with the cornea to focus light correctly on the retina.
The cornea transmits and focuses light into the eye. The colored part of the eye. The shape of the cornea does not change with the exception of small changes that occur offer a lifetime.
