Document Summary
Understanding the visual system requires in integration of two types of research: 1) research that probes the visual system with sophisticated neuroanatomical, neurochemical, and neurophysiological techniques and 2) research that focuses on the assessment of what we see. 6. 1 light enters the eye and reaches the retina. Light: waves of electromagnetic energy that are between 280 and 760 nanometers (10-9m) in length: wavelength: perception of colour. Irises: donut shaped bands of contractile tissue which give our eyes their characteristic colour. Eye position and binocular disparity: the movements of your eyes are coordinated so that each point in your visual word is projected to corresponding points on your two retinas. 6. 2 the retina and translation of light into neural signals. Light has to pass through to first 4 layers to get to the receptor layer: when all the retinal ganglion cell axon"s converge to form the optic nerve, they create a blind spot.
