The human eye is a complex organ that is able to detect and process light to create images.
The eye is divided into two main parts: the front part called the anterior segment, and the back part called the posterior segment.
The cornea, the clear front part of the eye, helps to focus light into the eye. The iris, the colored part of the eye, controls the amount of light that enters the eye by adjusting the size of the pupil.
The lens, located just behind the iris, further focuses light onto the retina, the light-sensitive layer of cells at the back of the eye.
The retina contains cells called rods and cones that detect light and convert it into electrical signals that are sent to the brain via the optic nerve.
The macula is a small, sensitive area of the retina that is responsible for central vision and color perception.
The eye produces tears to keep the surface of the eye moist and to protect it from infection.
The eye is able to adjust its focus to see objects at different distances through a process called accommodation.
The eye can move in all directions to track moving objects, this process is called saccades.
The eye has a built-in defense mechanism against harmful UV rays called the eyelid, which can close to protect the eye from bright light and foreign objects.
