Document Summary

Vision: humans are reliant on vision, ex. Introduction to light: eyes process light to visualize the world, detects light stimulus, takes are of initial stages of processing, sends results to brain for further processing. Amplitude: light travels as a whole, amplitude the height of each wave, an indication of perceives brightness, wavelengths distance between peaks of successive waves. Purity: an indication of colour saturation (cid:862)ri(cid:272)h(cid:374)ess(cid:863, natural light is a desaturated combination of many wavelengths, light (cid:373)ode up of a si(cid:374)gle (cid:449)a(cid:448)ele(cid:374)gth is (cid:863)pure light(cid:863, completely saturated. Iris controls the size of the pupil. Unit 4: the retina: the retina begins the translation of light into neural impulses. Retinal layer: paper thin sheet that covers the back of the eye and made up of neural cells arranged in. Vision: useful for peripheral vision, bipolar, nest layer in retina, ganglion, 3rd layer converge to form the optic nerve at the optic disc (exit hole in the eye.
