Cornea

Introduction to the topic

The cornea, also known as the stratum corneum, is the outermost part of the eyeball and plays an important role in its functioning. This transparent tissue contains many important structures such as the aqueous humor and the cornea. The article described here provides a description of the cornea, its functions, and diseases that can affect this area of ​​the eyeball.

What is the cornea of ​​the eye?

Aqueous humor fills the eye cavity, which is the inner part of the eye sac inside the head. From the back of the eye, fluids pass through a small channel to reach the cornea. The cornea is a very thin plate made up of whites and proteins that covers the inner surface of the eyeball towards the back and directly connects the front surface of the eye to the back. It is transparent, waterproof and has a hardness similar to glass. It is important to note that without the functioning of the cornea, the eyes would be unable to focus light and see objects up close.

Functions of the cornea

1. Protective shell. The cornea is the most protective layer of the eye as it protects the eye from the outside world and prevents foreign substances from entering it.

2. Transparency of light. The cornea has optical properties, such as the ability to refract and reflect light, which allows you to see objects both outside and inside the eye. When light passes through the cornea, it loses some energy, but this process is important for correctly seeing an object and determining its shape and color.

3. Participation in moisturizing the anterior surface of the eye. The cornea contains special protein structures that produce water
