Contact Lenses, Advantages and Disadvantages

Contact lenses can be a quite typical manner in which patients choose to correct their vision. They have several positive aspects over glasses, but sometimes cause problems too.
Advantages include better vision due to correction on the outside with the eye, and handle field of vision.
Several problems can happen because of contact lens wear too, so care has to be taken to avoid these complaints. Many doctors refer their patients to ophthalmolgists for evaluation and treatments for their lens related problems.
How can disposable lenses damage the eye?
Contacts could cause many problems in the eye, but only a couple of commonly encountered diagnoses can 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 contacts, either too many hours each day, or too many days consecutively. Symptoms include itching, inability to wear lenses for hours on end, and mucous discharge.
Punctate Keratopathy
Overwear also can create a problem on the outside with the cornea, where the top best contact solution

layer of cells are damaged. The eye doctor sees tiny pinpoint scratches about the cornea caused by decreased oxygen to those cells.
The most risk of a threat to vision could be the corneal ulcer. In this case, bacteria penetrates the surface of the cornea, causing infection that appears as a white spot. If untreated, this infection can penetrate and cause infection inside the eye.
How can we prevent contacts problems?
The most crucial thing for patients to complete is control their contact lens wear. Although many lenses are created and approved for overnight wear for between 2 and four weeks, most eye doctors recommend nightly removal and cleaning. The single most frequent cause of lens related problems is overwear, and a large study established that overnight wear is fourteen times more likely to cause ulcers than any other risk factor.
Are there safer alternatives to wearing contact lenses?
Of course, glasses would be the safest strategy 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, since they will be away from the eyes, the usually do not give vision that is certainly as sharp as contact lenses. Rigid or hard lenses are best of all because they float on the outside of the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also reveal that LASIK has less risks than contact lenses, though it may be a surgery. It is considerably more common for contacts to cause infection, inflammation etc vs. LASIK.
