How can disposable lenses damage the eye?
Contacts can cause many problems in the eye, but only a couple of commonly encountered diagnoses might cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration include the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs on account of overwear of lenses, either a lot of hours each day, or too many days back to back. Symptoms include itching, inability to wear lenses throughout the day, and mucous discharge.
Punctate Keratopathy
Overwear can also result in a problem on the outside of the cornea, in which the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches about the cornea due to decreased oxygen to those cells.
The most potential for a threat to vision will be the corneal ulcer. In this case, bacteria penetrates the surface in the cornea, causing infection that appears as a white spot. If untreated, this infection can penetrate and cause infection inside a persons vision.

Of course, glasses would be the safest strategy to correct vision without running the risk of contact lenses. Since glasses do not touch the eyes, they can’t create problems. On the other hand, since they will be away from the eyes, the usually do not give vision which is as sharp as contact lenses. Rigid or hard contacts are even better simply because they float on top of the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also demonstrate that LASIK has less risks than contact lenses, this specific a surgery. It is a lot more common for contacts to cause infection, inflammation etc vs. LASIK.
