Anatomy of the Eye
The Anatomy of the Eye
Throughout this website, you will note that we refer the eye as analogous to a camera:
- The cornea, which is the transparent covering on the front of the eye, acts much like a lens cover and a focussing element by bending entering light rays through the central ‘black hole’; the pupil, which combined with the coloured iris, the shutter, acts like the aperture of a camera.
- The lens is the next component in line and acts like the lens in a camera by its ability to focus light onto the retina, which acts very much like the film of the camera.
- The retina contains many light sensitive nerve cells called photoreceptors which transmit the light rays into electrical impulses which are delivered to the brain via the optic nerve where an image is perceived.
