Contact Lenses, Advantages and Disadvantages

Contact lenses can be a common way that patients choose to correct their vision. They have several advantages over glasses, but tend to make trouble too.
Advantages include better vision as a result of correction on the outside of the eye, and finished field of vision.
Several problems can happen due to contact wear too, so care has to be taken to avoid these problems. Many doctors refer their patients to ophthalmolgists for evaluation and treatment of their lens related problems.
How can disposable lenses damage the eye?
Contacts can cause many problems in the attention, but only several commonly encountered diagnoses could cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration would be the best contact solution

three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs on account of overwear of contacts, either too many hours per day, or lots of days consecutively. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear also can result in a problem on top from the cornea, where the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches for the cornea brought on by decreased oxygen to those cells.
The most possibility of a threat to vision will be the corneal ulcer. In this case, bacteria penetrates the surface of the cornea, causing an infection that appears as a white spot. If untreated, this infection can penetrate and cause infection inside a person’s eye.
How will we prevent contact lens problems?
The most crucial thing for patients to do is control their contacts wear. Although many lenses were created and approved for overnight wear for between 2 and 4 weeks, most eye doctors recommend nightly removal and cleaning. The single most popular source of contact related problems is overwear, as well as a large study indicated that overnight wear is fourteen times prone to cause ulcers than every other risk factor.
Are there safer alternatives to wearing lenses?
Of course, glasses would be the safest way to correct vision without running the potential risk of contact lenses. Since glasses tend not to touch the eye area, they won’t cause problems. On the other hand, since they will be away from your eyes, the tend not to give vision which is as sharp as disposable lenses. Rigid or hard lenses are even better given that they float at first glance in the eye, effectively smoothing out any rough spots, giving the best vision.
Recent studies also reveal that LASIK has less risks than contacts, even though it is a surgery. It is considerably more common for lenses to cause infection, inflammation etc vs. LASIK.
