GPC occurs due to overwear of contacts, either way too many hours every day, or too many days consecutively. Symptoms include itching, inability to wear lenses throughout the day, and mucous discharge.
Overwear can also cause a problem on top from the cornea, in which the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches about the cornea a result of decreased oxygen to those cells.
The most prospect of a threat to vision may be the corneal ulcer. In this case, bacteria penetrates the surface from the cornea, causing contamination that looks like a white spot. If untreated, this infection can penetrate and cause infection inside a person’s eye.
