The average eyeball is about the same size as a ping pong ball. There are 20 working parts in your eye, which sounds like a lot, but considering everything it does it really isn’t that many.
The eye works like this:
- Light enters the cornea, the clear front surface of the eye.
- The light then travels through the Iris, which controls the amount of light that reaches the back of the eye by adjusting the size of the pupil.
- The Crystalline Lens, located directly behind the pupil, further focuses the light through a process called accommodation, which helps the eye focus on its subject.
- Focused light then reaches the Retina, the inner lining of the back of the eye. The Retina converts images into electronic signals that are sent to the Optic Nerve and then gets sent to the Visual Cortex of the brain.
The eye does all of those things faster than you even realize what is happening. So again, take a minute to really think about how awesome the eye is. Now go out and see all the cool things your eyes were made to see!
