If you’re reading this, you’re currently using one of the most amazing organs that you possess: the eye. Your eyes detect light and convert it into impulses read by your brain, creating images and allowing you to see the world around you. The eye is an extremely complicated organ, but it doesn’t mean that you can’t familiarize yourself with its basic structure.
The Iris, Cornea and Pupil:
The eye has many parts that allow it to function, but you’re probably most familiar with these three exterior parts:
The cornea is the transparent part of your eye that covers the front of your eyeball. It refracts light as it enters the pupil, which is the black part in the center of your eye. Light goes through the pupil in order to reach the inner parts of your eye that are sensitive to light. The iris is the colorful ring of muscles around your pupil. The job of the iris is to regulate how much light enters the pupil by causing it to dilate or shrink.
The interior of your eye contains many parts that work together to process light before the optic nerve sends electrical impulses to your brain to process as an image. These interior parts include:
- Ciliary Body
From the lens which focuses light rays, to the fovea which is densely packed with cells that help you to process fine visual details, the human eye is a masterpiece of nature.
