How can disposable lenses damage the eye?
Contacts may cause many problems in a persons vision, but only several commonly encountered diagnoses may cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration are the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs on account of overwear of lenses, either a lot of hours daily, or too many days consecutively. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear also can lead to a problem on top in the cornea, where the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches around the cornea a result of decreased oxygen to those cells.
The most prospect of a threat to vision is the corneal ulcer. In this case, bacteria penetrates the surface with the cornea, causing infection that looks like a white spot. If untreated, this infection can penetrate and cause infection inside a person’s eye.

On the other hand, being that they are away from your eye area, the do not give vision which is as sharp as lenses. Rigid or hard contacts are better still given that they float on the outside with the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also reveal that LASIK has less risks than lenses, even though it is a surgery. It is much more common for contacts to cause infection, inflammation etc vs. LASIK.
