How can contacts damage the attention?
Contacts could cause many problems in a person’s eye, but only a number 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 contact lenses, either way too many hours each day, or way too many days back to back. Symptoms include itching, inability to wear lenses all day, and mucous discharge.
Punctate Keratopathy
Overwear can also cause a problem on the outside in the cornea, where the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches for the cornea a result of decreased oxygen to the people cells.
The most potential for a threat to vision is the corneal ulcer. In this case, bacteria penetrates the surface in the cornea, causing contamination that seems as a white spot. If untreated, this infection can penetrate and cause infection inside a person’s eye.
How can we prevent contact problems?
The most important thing for patients to do is control their lens wear. Although many lenses were created and approved for overnight wear for between 2 and a month, most eye doctors recommend nightly removal and cleaning. The single most popular source of contacts related problems is overwear, plus a large study demonstrated that overnight wear is fourteen times very likely to cause ulcers than some other risk factor.
Are there safer choices to wearing lenses?
Of course, glasses are the safest method to correct vision without running the risk of contacts. Since glasses don’t touch your eye area, they won’t create problems. On the other hand, because they are away from the eye area, the don’t give vision which is as sharp as contact lenses. Rigid or hard contacts are better yet simply because they float at first glance of the eye, effectively smoothing out any rough spots, giving the top vision.
Recent studies also demonstrate that LASIK has less risks than contacts, while it’s a surgery. It is much more common for contact lenses to cause infection, inflammation etc vs. LASIK.
