The anatomy of the visual system is extremely complex, so our discussion here will focus only on basic characteristics. The physical object being seen becomes an electrical impulse that is sent through the optic nerve to the visual center of the brain, the occipital lobes. Before reaching the optic nerve, light rays reflecting off the object being seen pass through several structures within the eye. The light rays do the following: 1. Pass through the cornea (a transparent cover in front of the iris and pupil), which performs the major part of the bending (refraction) of the light rays so that the image will be focused 2 Pass through the aqueous humor (a watery substance between the cornea and lens of the eye) 3, Pass through the pupil (the contractile opening in the middle of the iris, the colored portion of the eye that contracts or expands, depending on the amount of light striking it) 4. Pass through the lens, which refines and changes the focus of the light rays before they pass through the vitreous humor (a transparent gelatinous substance that fills the eyeball between the retina and lens) 5. come to a focus on the retina (the back portion of the eye, containing nerve fibers connected to the optic nerve, which carries the information back to the brain).
The main components of the eye include: Cornea - a transparent cover in front of the iris and pupil in the eye; responsible for most of the refraction of light rays in focusing on an object. Aqucous humor - a watery substance between the cornea and lens of the eye. Рupil - the contractile opening in the middle of the iris of the eye. Iris - the colored portion of the eye; contracts or expands, depending on the amount of light striking it. Lens - a structure that refines and changes the focus of the light rays passing through the eye. Vitreous humor - substance that fills the eyeball between the retina and the lens of the eye. Retina - the back portion of the eye, containing nerve fibers connected to the optic nerve.
