What harm does cosmetic contact lens have to eyes?

Cosmetic contact lenses will make the cornea unable to contact the air, and the eyes will have a situation similar to the human body's "altitude sickness" due to lack of oxygen, resulting in abnormal metabolism and decreased resistance.

Wearing cosmetic contact lenses for a long time will lead to corneal hypoxia and eye infection, which will seriously lead to eye diseases such as corneal perforation and even permanent blindness.

Generally speaking, people with conjunctivitis or ocular surface diseases cannot wear contact lenses or cosmetic contact lenses. If not, go to the hospital to check for trachoma or conjunctivitis. Don't wear it if you don't need advice. It's bad for your eyes.

Extended data:

Usually, you should be careful not to sleep overnight with contact lenses, which will do great harm to your eyes and cause corneal edema. Some people will get inflammation when they wear contact lenses, because the eyes themselves have potential inflammation before, but the biggest source is that after wearing cosmetic contact lenses, they usually do not pay attention to hygiene, leading to bacterial infection and inflammation.
