Study Notes
- The eye is composed of the eyeball, which can be visualized as a transparent ball, and various structures within it.
- The iris is the most visible part of the eye and determines eye color based on the pigment in the iris that reflects light.
- The pupil is the central hole in the iris through which light enters the eye.
- The iris regulates the size of the pupil to control the amount of light entering the eye based on ambient lighting conditions.
- The cornea is the bulge at the front of the eye and is a convex-shaped, watery substance called aqueous humor fills the space between the cornea and lens.
- The cornea, aqueous humor, and lens together form a converging lens system that focuses light on the retina.
- The retina is the light-sensitive cell covering at the back of the eye and converts light into electrical signals that are carried to the brain through optic nerves.
- The vitreous humor is a transparent, jelly-like substance that maintains the shape of the eye and provides structural support.
- The ciliary muscles are fibers that keep the lens in place and change the shape of the lens to adjust the optical power depending on the viewing distance, a phenomenon called accommodation.
