The document summarizes the anatomy and structures of the human eye. It describes the eyelid, lacrimal system, cornea, aqueous humor, limbus, conjunctiva, sclera, iris, lens, ciliary body, zonules, vitreous, choroid, retina, intra-ocular muscles, optic nerve, and optic nerve pathways. Key structures include the cornea which refracts light, the iris which controls pupil size, the lens which also refracts light, and the retina which converts light to electrical signals sent to the brain. The optic nerve transmits these signals from the eye to the visual cortex in the brain.
