GPC occurs because of overwear of lenses, either lots of hours every day, or too many days consecutively. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.

Overwear may also create a problem on top from the cornea, in which the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches for the cornea a result of decreased oxygen to those cells.
The most potential for a threat to vision may be the corneal ulcer. In this case, bacteria penetrates the surface from the cornea, causing disease that appears as a white spot. If untreated, this infection can penetrate and cause infection inside the attention.
How are we able to prevent contacts problems?
The most significant thing for patients to perform is control their contact lens wear. Although many lenses are made and approved for overnight wear for between 2 and 4 weeks, most eye doctors recommend nightly removal and cleaning. The single most frequent source of contact related problems is overwear, as well as a large study indicated that overnight wear is fourteen times more likely to cause ulcers than any other risk factor.
Are there safer alternatives to wearing lenses?
Of course, glasses include the safest approach to correct vision without running potential risk of contact lenses. Since glasses do not touch the eye area, they can’t make trouble. On the other hand, being that they are away from your eyes, the do not give vision that is certainly as sharp as lenses. Rigid or hard contacts are better yet because they float on the surface of the eye, effectively smoothing out any rough spots, giving the best vision.
Recent studies also demonstrate that LASIK has less risks than contacts, this specific a surgery. It is considerably more common for contact lenses to cause infection, inflammation etc vs. LASIK.
