What is the eye surface?

The eye surface is the surface of the human eye. This includes the cornea, conjunctiva and tears that connect to them. The definition also sometimes includes lids.

The cornea is the easiestly recognizable part of the eye surface. It consists of a clean piece of tissue that covers the iris. From the side it looks like a dome. The cornea protects the sensitive iris and at the same time allows the light to reach the pupil, leading to the lenses and cone -reducing the light of the inner eye.

The nerve endings also form a cornea. These help feel when there is something in the eye and signal tears to create more fluids to get out. The corneal sensitivity also means that some people cannot easily wear contacts. Like the cornea, it is also clear. It is assumed that Cojuntiva has three parts: a part that a blanket eye, a part that lines the inside of the eyelids, and the part where these two surfaces meet when the eye is closed.

This area producesmucus and some fluid. This keeps the eye surface wet and greased so that the eyes can flash easily. It is nourished by many blood vessels. If they become infected, these blood vessels can become red and inflamed. This disease is known as "Pinkeye".

Finally, tear channels are also considered part of the eye surface. There is one in each corner of the eye. They produce tears that cover and smear the eye surface. If these channels become clogged or otherwise unable to produce tears, the resulting lack of tears and dryness may be very painful.

eyelids have two purpose. Protects the rest of the eye from dust and debris. Also, the effect of flashing spreads tears over the eye to maintain it.

At the beginning of 2000, an inspection magazine called eye surface was created to support the research and development of disorders that affect the eye surface. They try to provide a place where hundreds of new studies can easily be accessed.
