Contact Lenses, Advantages and Disadvantages

Contact lenses certainly are a very common 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 on the outside in the eye, and complete field of vision.
Several problems may appear on account of lens wear too, so care have to be taken up avoid these complaints. Many doctors refer their patients to ophthalmolgists for evaluation and management of their lens related problems.
How can disposable lenses damage a person’s eye?
Contacts may cause many problems in a persons vision, but only several commonly encountered diagnoses can cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration will be the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs as a result of overwear of disposable lenses, either way too many hours every day, or too many days consecutively. Symptoms include itching, inability to wear lenses throughout the day, and mucous discharge.
Punctate Keratopathy
Overwear may also cause a problem on top from the cornea, the location where the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches for the cornea a result of decreased oxygen to the people cells.
The most risk of a threat to vision will be the corneal ulcer. In this case, bacteria penetrates best contact solution

the surface in the cornea, causing infection that appears as a white spot. If untreated, this infection can penetrate and cause infection inside a persons vision.
How will we prevent contacts problems?
The most significant thing for patients to perform is control their contact wear. Although many lenses are created and approved for overnight wear for between 2 and 4 weeks, most eye doctors recommend nightly removal and cleaning. The single most frequent cause of contacts related problems is overwear, plus a large study demonstrated that overnight wear is fourteen times more prone to cause ulcers than any other risk factor.
Are there safer alternatives to wearing contact lenses?
Of course, glasses will be the safest strategy to correct vision without running the chance of contacts. Since glasses don’t touch the eye area, they won’t lead to further problems. On the other hand, since they are away from the eye area, the usually do not give vision that’s as sharp as lenses. Rigid or hard disposable lenses are best of all given that they float on the outside in the eye, effectively smoothing out any rough spots, giving the best vision.
Recent studies also show that LASIK has less risks than contacts, this specific a surgery. It is far more common for lenses to cause infection, inflammation etc vs. LASIK.
