THE HUMAN EYE!!! SCIENCE

The human eye  is an organ that reacts to light and has several purposes. As a sense organ, the mammalian eye allows vision. Rodand cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors.

Similar to the eyes of other mammals, the human eye's non-image-forming photosensitive ganglion cells in the retina receive light signals which affect adjustment of the size of the pupil, regulation and suppression of the hormone melatonin and entrainment of thebody clock.
