Contact Lenses, Advantages and Disadvantages

Contact lenses really are a very common method that patients choose to correct their vision. They have several advantages over glasses, but could make trouble too.
Advantages include better vision on account of correction on the surface with the eye, and finished field of vision.
Several problems can happen on account of contacts wear too, so care must be delivered to avoid these problems. Many doctors refer their patients to ophthalmolgists for evaluation and management of their lens related problems.
How can contacts damage the attention?
Contacts could cause many problems in a persons vision, but only a couple of commonly encountered diagnoses may 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 contact lenses, either a lot of hours each day, or too many days back to back. Symptoms include itching, inability to wear lenses all day, and mucous discharge.
Punctate Keratopathy
Overwear may also lead to a problem on top with the cornea, the place that the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches

on the cornea due to decreased oxygen to those cells.
Ulceration
The most potential for a threat to vision could be the corneal ulcer. In this case, bacteria penetrates the surface with the cornea, causing an infection that looks like a white spot. If untreated, this infection can penetrate and cause infection inside a person’s eye.
How will we prevent contacts problems?
The most crucial thing for patients to accomplish is control their lens wear. Although many lenses are created and approved for overnight wear for between 2 and a month, most eye doctors recommend nightly removal and cleaning. The single most typical reason for contact 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 strategy to correct vision without running potential risk of contacts. Since glasses tend not to touch the eye area, they can’t create problems. On the other hand, since they will be away from your eyes, the tend not to give vision that is as sharp as contact lenses. Rigid or hard disposable lenses are even better given that they float on the outside from the eye, effectively smoothing out any rough spots, giving the most effective vision.
Recent studies also show that LASIK has less risks than contacts, even though it is a surgery. It is far more common for disposable lenses to cause infection, inflammation etc vs. LASIK.
