Keratoconus
Keratoconus is a disease caused by thinning and sharpening of the transparent layer of the eye, namely the cornea, with progressive myopia and astigmatism. Patients are aware of the disease, which usually starts in adolescence, only in their 20s. The disease progresses between the ages of 20 and 40 and enters the stationary period after the age of 40. The cornea is a very important part of the eye. Light enters the eye through the cornea. It allows you to see clearly by refracting or focusing the rays. In keratoconus, vision is impaired because the cornea is damaged. Keratoconus can make some activities difficult, such as driving a car, typing on a computer, watching television, or reading.

- Ultraviolet rays
- Eye rub
- Environmental factors
- Use of hard contact lenses

Although the cause of keratoconus disease is not known exactly as a result of the researches, genetic and mechanical traumas play the most important role in its development.
