Contact Lenses, Advantages and Disadvantages
Contact lenses are a quite normal method that patients elect to correct their vision. They have several positive aspects over glasses, but could create problems too.
Advantages include better vision as a result of correction on the outside of the eye, and complete field of vision.
Several problems can occur due to contact lens wear too, so care has to be delivered to avoid these problems. Many doctors refer their patients to ophthalmolgists for evaluation and treatment of their lens related problems.
How can contact lenses damage a person’s eye?
Contacts could cause many problems in the attention, but only several commonly encountered diagnoses can cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration are the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs because of overwear of disposable lenses, either lots of hours each day, or a lot of days in a row. Symptoms include itching, inability to wear lenses throughout the day, and mucous discharge.
Overwear can also result in a problem on the surface from the cornea, in which the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches on the cornea brought on by decreased oxygen to 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 looks like a white spot. If untreated, this infection can penetrate and cause infection inside a persons vision.
How can we prevent contact problems?
The most important thing for patients to complete is control their lens wear. Although many lenses are designed and approved for overnight wear for between 2 and 30 days, most eye doctors recommend nightly removal and cleaning. The single most frequent source of contacts related problems is overwear, plus a large study demonstrated that overnight wear is fourteen times prone to cause ulcers than some other risk factor.
Are there safer options to wearing lenses?
Of course, glasses are the safest approach to correct vision without running the risk of lenses. Since glasses do not touch the eye area, they won’t cause problems. On the other hand,

best contact solution for sensitive eyes being that they are away from your eyes, the tend not to give vision which is as sharp as lenses. Rigid or hard contacts are better yet since they float on top of the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also reveal that LASIK has less risks than lenses, even though it is a surgery. It is far more common for contact lenses to cause infection, inflammation etc vs. LASIK.
