Contact Lenses, Advantages and Disadvantages

Contact lenses are a common manner in which patients tend to correct their vision. They have several advantages over glasses, but could lead to further problems too.
Advantages include better vision on account of correction on the surface of the eye, and handle field of vision.
Several problems can happen due to lens wear too, so care must be come to avoid these problems. Many doctors refer their patients to ophthalmolgists for evaluation and treating their lens related problems.
How can contact lenses damage the eye?
Contacts can 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.

GPC occurs on account of overwear of lenses, either too many hours daily, or too many days in a row. Symptoms include itching, inability to wear lenses throughout the day, and mucous discharge.
Punctate Keratopathy
Overwear can also cause a problem on the surface in the cornea, the place that the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches for the cornea brought on by decreased oxygen to people cells.
Ulceration
The most potential for a threat to vision may be the corneal ulcer. In this case, bacteria penetrates the surface of the cornea, causing contamination that appears as a white spot. If untreated, this infection can penetrate and cause infection inside a persons vision.
How will we prevent lens problems?
The most important thing for patients to perform is control their contact 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 frequent reason behind contact lens related problems is overwear, along with a large study showed that overnight wear is fourteen times prone to cause ulcers than every other risk factor.
Are there safer choices to wearing contacts?
Of course, glasses will be the safest way to correct vision without running potential risk of contact lenses. Since glasses don’t touch your eye area, they can not create problems. On the other hand, being that they are away from your eyes, the do not give vision that is certainly as sharp as contact lenses. Rigid or hard disposable lenses are best of all given that they float on top of the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also demonstrate that LASIK has less risks than disposable lenses, though it may be a surgery. It is considerably more common for disposable lenses to cause infection, inflammation etc vs. LASIK.
