How can lenses damage the attention?
Contacts might cause many problems in the eye, but only a number of 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 as a result of overwear of contacts, either too many hours every day, or a lot of days in a row. Symptoms include itching, inability to wear lenses all day, and mucous discharge.
Punctate Keratopathy
Overwear can also result in a problem on the surface of the cornea, in which the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches for the cornea brought on by decreased oxygen to the people cells.
Ulceration
The most possibility of 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 person’s eye.

On the other hand, since they will be away from the eye area, the do not give vision that is certainly as sharp as contact lenses. Rigid or hard contact lenses are even better because they float on the surface with the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also demonstrate that LASIK has less risks than disposable lenses, though it may be a surgery. It is far more common for contacts to cause infection, inflammation etc vs. LASIK.
