Human Eye
... Biology " The Human Eye " The human eye is the organ which gives us the sense of sight. ... The eye allows us to see and interpret the shapes, colors, and dimensions of objects in the world by processing the light they reflect. The eye is able to see in bright light or in dim light, but it cannot see objects when light is absent. Light waves from an object enter the eye first through the clear cornea and then through the pupil, the circular part in the iris. ... The retina is the innermost layer of the eye and is comparable to the film inside of a camera.
