Eye parts and functions. The sclera or white part of the eye protects the eyeball.
Anatomy And Function Of The Eye
It converts light into electrical impulses.
Eye anatomy and function. The cornea is basically eyes outer covering. The eye has many parts that must work together to produce clear vision. The anatomy of the eye when you look at an eye you can see some of the outer and middle layers.
The iris uses muscles to change the size of the pupil. The iris or coloured part of the eye surrounds the pupil. It is generally dome shaped layer and its main function is to protect your eye from foreign substances which may damage the eyes inner portion.

This can help you appreciate just why it is so critical to take good care of your eyes.

The eyes crystalline lens is located directly behind the pupil and further focuses light. The iris controls the amount of light that enters the eye by opening and closing the pupil. Retina the light sensitive layer within the eye that converts images into electrical signals.
Nerve signals that contain visual information are transmitted through the optic nerve to the brain. Cornea comprised of several layers which create a tough layer which provides additional support and protection. The surface of the eye and of the inner eyelids is covered by a clear protective membrane called the conjunctiva.
These muscles can control the amount of light entering the eye by making the pupil larger dilated or smaller constricted. The pupil or black dot at the centre of the eye is an opening through which light can enter the eye. The anatomy of the eye.
Eye parts description and functions. By learning about eye anatomy and function you will see how each small feature of the eye plays a major part. The eye has many parts which work together to accomplish vision and to keep the structures required for vision safe from infection and injury.
