Contact Lenses, Advantages and Disadvantages

Contact lenses certainly are a quite typical way that patients choose to correct their vision. They have several positive aspects over glasses, but tend to create problems too.
Advantages include better vision on account of correction on the surface of the eye, and finish field of vision.
Several problems can occur because of contact wear too, so care has to be come to avoid these issues. Many doctors refer their patients to ophthalmolgists for evaluation and treatment of their lens related problems.
How can contacts 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.
Giant Papillary Conjunctivitis (GPC)
GPC occurs as a result of overwear of disposable lenses, either a lot of hours daily, or lots of days consecutively. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear could also cause a problem on the outside of 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 prospects cells.
Ulceration
The most possibility of a threat to vision may be the corneal ulcer. In this case, bacteria penetrates the surface from the cornea, causing contamination that appears as a white best contact solution

spot. If untreated, this infection can penetrate and cause infection inside a person’s eye.
How will we prevent contacts problems?
The most significant thing for patients to do is control their contacts wear. Although many lenses are designed and approved for overnight wear for between 2 and a month, most eye doctors recommend nightly removal and cleaning. The single most frequent reason behind contact related problems is overwear, as well as a large study showed that overnight wear is fourteen times more likely to cause ulcers than another risk factor.
Are there safer choices to wearing contact lenses?
Of course, glasses will be the safest method to correct vision without running the potential risk of disposable lenses. Since glasses do not touch your eye area, they can not create problems. On the other hand, since they will be away from the eye area, the tend not to give vision that’s as sharp as lenses. Rigid or hard lenses are best of all given that they float on top from the eye, effectively smoothing out any rough spots, giving the best vision.
Recent studies also demonstrate that LASIK has less risks than disposable lenses, even though it is a surgery. It is much more common for contact lenses to cause infection, inflammation etc vs. LASIK.
