Contact Lenses, Advantages and Disadvantages

Contact lenses are a quite normal way that patients elect to correct their vision. They have several advantages over glasses, but can create problems too.
Advantages include better vision on account of correction on top in the eye, and handle field of vision.
Several problems can take place due to contact lens wear too, so care has to be taken up avoid these issues. Many doctors refer their patients to ophthalmolgists for evaluation and treatment of their lens related problems.
How can lenses damage a persons vision?
Contacts might cause many problems in the eye, but only a couple of commonly encountered diagnoses could cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration will be the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs as a result of overwear of contact lenses, either lots of hours daily, or way too many days consecutively. Symptoms include itching, inability to wear lenses for hours on end, and mucous discharge.
Punctate Keratopathy
Overwear also can lead to a problem at first glance in the cornea, the place that the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches around the cornea brought on by decreased oxygen to

Ulceration
The most risk of a threat to vision is the corneal ulcer. In this case, bacteria penetrates the surface in the cornea, causing infection that looks like a white spot. If untreated, this infection can penetrate and cause infection inside the eye.
How could we prevent contacts problems?
The most important thing for patients to complete is control their contacts wear. Although many lenses are created and approved for overnight wear for between 2 and 30 days, most eye doctors recommend nightly removal and cleaning. The single most common source of contact lens related problems is overwear, and a large study demonstrated that overnight wear is fourteen times very likely to cause ulcers than every other risk factor.
Are there safer choices to wearing contacts?
Of course, glasses will be the safest strategy to correct vision without running the potential risk of disposable lenses. Since glasses do not touch the eyes, they won’t lead to further problems. On the other hand, because they are away from your eye area, the tend not to give vision which is as sharp as disposable lenses. Rigid or hard disposable lenses are better still because they float on the surface from the eye, effectively smoothing out any rough spots, giving the most effective vision.
Recent studies also reveal that LASIK has less risks than lenses, this specific a surgery. It is considerably more common for contacts to cause infection, inflammation etc vs. LASIK.
