How eye works

The individual components of the eye work in a manner similar to a camera. Each part plays



a vital role in providing clear vision. So think of the eye as a camera with the cornea, behaving


much like a lens cover. As the eye's main focusing element, the cornea takes widely diverging


rays of light and bends them through the pupil, the dark, round opening in the center of the


colored iris. The iris and pupil act like the aperture of a camera.






Next in line is the lens which acts like the lens in a camera, helping to focus light to the back


of the eye. Note that the lens is the part which becomes cloudy and is removed during cataract


surgery to be replaced by an artificial implant nowadays.
