Contact Lenses, Advantages and Disadvantages

Contact lenses are a quite typical method in which patients choose to correct their vision. They have several advantages over glasses, but sometimes make trouble too.
Advantages include better vision on account of correction at first glance with the eye, and complete field of vision.
Several problems can take place as a result of contact lens wear too, so care should be taken up avoid these complaints. Many doctors refer their patients to ophthalmolgists for evaluation and treatment of their lens related problems.
How can lenses damage the eye?
Contacts might cause many problems in the eye, but only a number of commonly encountered diagnoses might 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 disposable lenses, either a lot of hours every day, or a lot of days in a row. Symptoms include itching, inability to wear lenses for

Punctate Keratopathy
Overwear also can create a problem on the outside with the cornea, the location where the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches around the cornea caused by decreased oxygen to prospects cells.
The most prospect of a threat to vision could be the corneal ulcer. In this case, bacteria penetrates the surface with the cornea, causing disease that appears as a white spot. If untreated, this infection can penetrate and cause infection inside the attention.
How can we prevent contacts problems?
The most critical thing for patients to accomplish is control their contact wear. Although many lenses are created and approved for overnight wear for between 2 and four weeks, most eye doctors recommend nightly removal and cleaning. The single most typical cause of contacts related problems is overwear, plus a large study demonstrated that overnight wear is fourteen times more likely to cause ulcers than some other risk factor.
Are there safer alternatives to wearing contacts?
Of course, glasses are the safest way to correct vision without running the potential risk of contacts. Since glasses don’t touch your eye area, they cannot make trouble. On the other hand, since they are away from your eye area, the tend not to give vision which is as sharp as lenses. Rigid or hard disposable lenses are better yet given that they float on the outside with the eye, effectively smoothing out any rough spots, giving the most effective vision.
Recent studies also show that LASIK has less risks than disposable lenses, even though it is a surgery. It is much more common for contacts to cause infection, inflammation etc vs. LASIK.
