Physiology of Vision

• Light enters eye along visual axis • Pupil and lens accommodate • Light is refracted: cornea, aqueous humor, lens,

vitreous body

• An inverted image is projected onto retina • Photoreceptors are stimulated • Visual pathways distribute information from

each eye to the visual cortex of both cerebral hemispheres
