can anyone easily explain human eye?
Answers
Explanation:
this is clear information
Explanation:
The human eye is like a camera. It's lens system forms an image on a light sensitive screen called the retina. Light enters the eye through a thin membrane called cornea. It forms the transparent bulge on the front surface of the eyeball. Most of the refraction for the light rays entering the eye occurs at the outer surface of the cornea. The crystalline lens merely provides the finner adjustment of focal length required to focus objects at different distances on the retina. Iris is a dark muscular diaphragm that controls the size of pupil. The pupil regulates and controls the amount of light entering the eye. The eye lens forms an inverted real image of the object on the retina. The retina is a delicate membrane having enormous number of light sensitive cells. The light sensitive cells get activated upon illumination and generate electrical signals . These signals are sent to brain via the optic nerves. The brain interprets these signals, and processes the information so that we perceive objects as they are.
