Contact Lenses, Advantages and Disadvantages

Contact lenses can be a quite typical method that patients decide to correct their vision. They have several advantages over glasses, but could create problems too.
Advantages include better vision due to correction on top of the eye, and handle field of vision.
Several problems can occur because of contact lens wear too, so care should be come to avoid these problems. Many doctors refer their patients to ophthalmolgists for evaluation and treatments for their lens related problems.
How can contacts damage a person’s eye?
Contacts could cause many problems in the eye, but only several commonly encountered diagnoses might cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration include the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs on account of overwear of lenses, either too many hours per day, or lots of days uninterruptedly. Symptoms include itching, inability to wear lenses for hours on end, and mucous discharge.
Punctate Keratopathy
Overwear can also lead to a problem on the outside from the cornea, the place that the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches around the cornea due to decreased oxygen to those cells.
Ulceration
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 seems as a white spot. If untreated, this infection can penetrate and cause infection inside a person’s eye.
How are we able to prevent lens problems?
The most significant thing for patients to do is control their lens wear. Although many lenses are made and approved for overnight wear for between 2 and 4 weeks, most eye doctors recommend nightly removal and cleaning. The single most common source of contacts related problems is overwear, and a large study established that overnight wear is fourteen times prone to cause ulcers than any other risk factor.
Are there safer choices to wearing contacts?

include the safest strategy to correct vision without running the chance of contact lenses. Since glasses tend not to touch your eye area, they cannot make trouble. On the other hand, being that they are away from the eyes, the do not give vision that is as sharp as disposable lenses. Rigid or hard disposable lenses are better yet simply because they float on the surface of the eye, effectively smoothing out any rough spots, giving the most effective vision.
Recent studies also demonstrate that LASIK has less risks than lenses, this specific a surgery. It is a lot more common for contacts to cause infection, inflammation etc vs. LASIK.
