The Human Eye. In many ways, the human eye is similar to a camera. Light enters through an opening, is focused through a lens, passes through a light-tight.

Electromagnetic Spectrum

Visible Light

Structure of the Eye Sclera – white outer structure that forms the body of the eye Cornea – Clear outer structure that collects light Lens – Clear inner structure that focuses light onto the retina Iris – Colored structure that controls the amount of light entering the eye Pupil – The orifice in the enter of the iris that light passes through Retina – Structure made up of light sensitive cells that line the back of the eye Optic Nerve – Bundle of nerves transmitting information from the eye to the brain

Structure of the Retina Rods – Highly sensitive light sensitive nerve cells Cone – Color sensitive nerve cells Bipolar Cells – Nerve cells that receive input from the rods and cones Fovea – Area of retina with high concentration of rods and cones – allows sharp detail vision Blind Spot – Place where the optic nerves passes through the retina

Visual Processing Images are inverted and reversed Visual processing starts in the retina Optic Chiasm – Left-right split of image from each eye – left to left brain, right to right brain

Color Vision & Color Blindness Humans can see about 7 million different colors Color Blindness: 1 in 50 men, 1 in 5,000 women Trichromatic color vision – Three different types of cones are sensitive to three different colors Opponent-process color vision – Higher level processing compares input from paired receptors in the eye to determine color information.Interactivity 9-1 (Show for Review)
