Human Eye

The human eye is one of the sensitive sense organs. Among all the sense organs, the human eye is one of the most important one which helps us to see the beautiful world around us. The structure of the eye is very interesting and surprising. The Human eye performs like a camera, where the objects are captured and given out as a real picture. The lens system in the structure of a human eye forms an image on a light sensitive screen called the retina. This lens forms an inverted real image of the object on the retina. The retina is a delicate membrane having lots of light sensitive cells. This light sensitive cell gets activated and generates electrical signals which are sent to the brain via optic nerves. The brain interprets these signals and processes the information which allows seeing objects.
