Contact Lenses, Advantages and Disadvantages
Contact lenses really best contact solution best contact solution are a quite typical method in which patients tend to correct their vision. They have several positive aspects over glasses, but sometimes lead to further problems too.
Advantages include better vision because of correction at first glance from the eye, and finished field of vision.
Several problems can take place due to contact lens wear too, so care should be taken to avoid these issues. Many doctors refer their patients to ophthalmolgists for evaluation and treatments for their lens related problems.
How can contact lenses damage a person’s eye?
Contacts might cause many problems in a person’s eye, but only a couple of 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 because of overwear of disposable lenses, either way too many hours each day, or lots of days uninterruptedly. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Overwear could also result in a problem on the surface of the cornea, the location where the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches about the cornea due to decreased oxygen to prospects cells.
The most potential for a threat to vision may be the corneal ulcer. In this case, bacteria penetrates the surface of the cornea, causing infection that seems as a white spot. If untreated, this infection can penetrate and cause infection inside a persons vision.
How can we prevent lens problems?
The most important thing for patients to perform is control their contact wear. Although many lenses were created and approved for overnight wear for between 2 and four weeks, most eye doctors recommend nightly removal and cleaning. The single most typical cause of lens related problems is overwear, as well as a large study indicated that overnight wear is fourteen times more likely to cause ulcers than every other risk factor.
Are there safer alternatives to wearing contact lenses?
Of course, glasses include the safest method to correct vision without running the chance of contact lenses. Since glasses tend not to touch the eye area, they cannot cause problems. On the other hand, being that they are away from your eye area, the don’t give vision that is as sharp as lenses. Rigid or hard contacts are better yet because they float on the surface in the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also show that LASIK has less risks than contacts, while it’s a surgery. It is far more common for contacts to cause infection, inflammation etc vs. LASIK.
