Document Summary

Module 18: vision and perceptual organization and interpretation. Our eyes receive light energy and transduce (transform) it into neural messages that our brain then processes into what we coconsciously see. What we see as visible light is a thin slice of the whole spectrum of electromagnetic energy: spectrum ranges from imperceptibly short gamma waves to the long waves of radio transmission. Light enters the eye through the cornea, which protects the eye and bends light to provide focus. The light then passes through the pupil, a small adjustable opening. Behind the pupil is a lens that focuses incoming light rays into an image on the retina, a multilayered tissue on the eyeball"s sensitive inner surface. The lens focuses the rays by changing its curvature in a process called your identity accommodation. After passing through the cornea it then passes through the pupil, a small adjustable opening.
