Eye is the organ of sight. It is our most important organ for finding out about the world around us. We use our eyes in almost everything we do — reading, working, watching movies and television, playing games, and countless other activities. Sight is our most precious sense, and many people fear blindness more than any other disability. The human eyeball measures only about 1 inch (25 millimeters) in diameter.

Instead, it sees the light they reflect or give off. The eye can see in bright light and in dim light, but it cannot see in no light at all. Light rays enter the eye through transparent tissues.
The eye changes the rays into electrical signals. The signals are then sent to the brain, which interprets them as visual images. This article deals mainly with the human eye. It discusses the parts of the eye, how we see, defects and diseases of the eye, and care of the eye. The last section of the article describes some of the differences in the eyes of various kinds of animals. Eye is the organ of sight.

The Essay on Gabor Holograms Light Object
Holography is the process of storing information reflected off objects via light and using that information to produce a photograph of that object. The photograph has characteristics that bear striking resemblance to that of the real object. Unlike regular photographs taken, holograms can show the observer different perspectives of the object rather then just the front of an object (Jeong & ...
