The human eye is one of the most vital parts of the human body due to the fact that we require the use of this sensory organ of sight to perform all of our daily activities. It is an educational experience to study the anatomy of the human eye. In the process of doing so we learn so many interesting facts that help us to gain a greater understanding of the essential functions of the eye. Therefore, we need to pay greater attention to maintaining the various parts of this organ so that our visual system works more efficiently. There are 3 major parts of the human eye. The first layer is called the sclerotic which is also known as the outer layer of the eyes. The middle layer of the eyes which is the second layer is called the choroid. The third layer which is also known as the inner layer of the eyes is called the retina. The cornea is part of the sclerotic and this part of the eye is defined as the thin, clear and transparent front surface of the eyes.Therefore, here are some of the reasons why the cornea is such an essential part of eye anatomy in vision function .

It is through the cornea that light images reflected off of objects first enters the eyes before the eye lens that light image and transmits it to the retina. Here the image is recorded and sent to the optic nerve where the brain then processes that image as the vision that we can see.

Therefore, the cornea is the part of the eye that is quite essential due to the fact that it facilitates the transmission of light images in the eyes and works in conjunction with other parts of the eyes so that light images fall directly on the retina enabling us to see images clearly.

Could you imagine what would happen if the cornea did not exist. We would basically go blind. This is due to the fact that light perception is an essential aspect of natural vision improvement as we can not see images properly without the proper lighting.

Additionally, the cornea is a part of the eyes that keeps the front surface of the eyes clean and free of bacteria and infections. This is due to the fact that it works in conjunction with tears to cleanse this part of the eyes. Therefore, the essential role of the cornea also includes protective properties essential to the maintenance of healthy eyesight.

The cornea is a part of the eye that plays an essential role in vision function. The functions of this important part of the eyes includes the following: protection from bacterial infections, proper transmission of light images form one part of the visual system to the next in order to facilitate clear eyesight when the image falls on the retina. This essential aspect of your eyes helps the function of the visual system in a variety of ways to make our eyes work in a more efficient manner for better eyesight without glasses.
