How can contact lenses damage a persons vision?
Contacts might cause many problems in the eye, but only several commonly encountered diagnoses can cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration are the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs as a result of overwear of contacts, either lots of hours every day, or best contact solution best contact solution way too many days consecutively. Symptoms include itching, inability to wear lenses throughout the day, and mucous discharge.
