The Eye's Structure and Functions
Cornea
- The transparent, dome-shaped surface at the front of the eye, responsible for refracting light and protecting the eye from dust, dirt, and other foreign particles.
Iris
- A colored, ring-shaped membrane that controls the amount of light entering the eye by adjusting the size of the pupil, ensuring proper light exposure for clear vision.
Retina
- The innermost layer of the eye, responsible for converting light into electrical signals that are transmitted to the brain, enabling us to perceive and interpret visual information.
