How can lenses damage a persons vision?
Contacts might cause many problems in the attention, but only a number of commonly encountered diagnoses may cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration will be the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs on account of overwear of contacts, either a lot of hours each day, or too many days uninterruptedly. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear could also lead to a problem on the surface in the cornea, in which the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches on the cornea a result of decreased oxygen to the people cells.
Ulceration
The most prospect of a threat to vision may be the corneal ulcer. In this case, bacteria penetrates the surface of the cornea, causing an infection that seems as a white spot. If untreated, this infection can penetrate and cause infection inside the eye.
How could we prevent lens problems?
The most critical thing for patients to accomplish is control their contacts wear. Although many lenses are made and approved for overnight wear for between 2 and four weeks, most eye doctors recommend nightly removal and cleaning. The single most typical reason for contact lens related problems is overwear, and a large study established that overnight wear is fourteen times more likely to cause ulcers than another risk factor.
Are there safer alternatives to wearing contact lenses?
Of course, glasses include the safest approach to correct vision without running the risk of disposable lenses. Since glasses usually do not touch your eyes, they won’t cause problems. On the other hand, since they are away from the eye area, the tend not to give vision that is as sharp as contacts. Rigid or hard contacts are even better simply because they float at first glance with the eye, effectively smoothing out any rough spots, giving the best vision.
Recent studies also demonstrate that LASIK has less risks than disposable lenses, even though it is a surgery. It is a lot more common for contacts to cause infection, inflammation etc vs. LASIK.
