Contact Lenses, Advantages and Disadvantages

Contact lenses are a quite typical way that patients elect to correct their vision. They have several positive aspects over glasses, but could cause problems too.
Advantages include better vision on account of correction on the surface of the eye, and complete field of vision.
Several problems can take place on account of lens wear too, so care must be taken to avoid these complaints. Many doctors refer their patients to ophthalmolgists for evaluation and treatment of their lens related problems.
How can contact lenses damage the eye?
Contacts could cause many problems in the eye, but only a number of commonly encountered diagnoses can cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration would be the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs because of overwear of disposable lenses, either too many hours every day, or a lot of days uninterruptedly. Symptoms include itching, inability to wear lenses for hours on end, and mucous discharge.
Punctate Keratopathy
Overwear may also create a problem on the outside of

Ulceration
The most potential for a threat to vision could be the corneal ulcer. In this case, bacteria penetrates the surface from the cornea, causing disease that looks like a white spot. If untreated, this infection can penetrate and cause infection inside the eye.
How can we prevent lens problems?
The most significant thing for patients to complete is control their contacts wear. Although many lenses are designed and approved for overnight wear for between 2 and four weeks, most eye doctors recommend nightly removal and cleaning. The single most popular reason behind contacts related problems is overwear, plus a large study established that overnight wear is fourteen times more likely to cause ulcers than every other risk factor.
Are there safer options to wearing contact lenses?
Of course, glasses include the safest strategy to correct vision without running the risk of contacts. Since glasses usually do not touch the eyes, they won’t make trouble. On the other hand, since they are away from your eye area, the tend not to give vision that is as sharp as disposable lenses. Rigid or hard lenses are better yet since they float on top from the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also show that LASIK has less risks than lenses, while it’s a surgery. It is a lot more common for disposable lenses to cause infection, inflammation etc vs. LASIK.
