WebIn brief, the mechanism of visual sensation is as follows: Light rays from external objects impinge on the human eye. The human eye is more or less similar to a camera. Just as the camera has a lens, the human eye also has a lens. The light rays pass through the lens and strike the inner layer of the eye known as the retina.
