The Anatomy of The Eyes

The Eyes

An organ located in the head, which allows the body to see.

What are the eyes main functions?

The eyes allow the human body to see, by sending signals from the retina, through to the brain via the optic nerve. Eyes are extremely complex organs, however there are certain frequencies of light it cannot see, such as ultraviolet light. Many people across the globe have eye problems, and wear glasses to assist the eyes with these. 

What the eyes look like, inside and out.

What are the eyes made of?

The eyes are made of thousands of tiny nerves, muscles, and discs. 

The pupil is the small black hole in the centre of the eye. It is surrounded by the iris; which is either a blue, green, or brown colour. The anterior chamber, located at the bottom of the iris, is a fluid-filled space. When you blink, the eyes are moistened with this fluid, and if you don't blink for a long time, your eyes will dry out. Luckily, the brain's neurons allow the eyes to blink automatically. 

The optic disc is at the back of the eyes. If you look a certain way, you are able to see the blindspot that this causes. The optic disc has no debris, such as cones or rods, covering it, so this is what causes it.

This will help you find your blindspot in the eye. It appears as a small, colourless dot, and is a cool trick to impress your friends.

The retina is where the optic nerve sends the brain information from. The optic nerve is of course, connected to the optic disc.
