Contact Lenses, Advantages and Disadvantages

Contact lenses can be a common way that patients choose to correct their vision. They have several positive aspects over glasses, but can create problems too.
Advantages include better vision because of correction on the surface from the eye, and finish field of vision.
Several problems can occur because of contacts wear too, so care has to be taken to avoid these problems. Many doctors refer their patients to ophthalmolgists for evaluation and treatments for their lens related problems.
How can disposable lenses damage the attention?
Contacts may cause many problems in a persons vision, but only several commonly encountered diagnoses might cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration will be the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs due to overwear of disposable lenses, either way too many hours every day, or too many days uninterruptedly. Symptoms include itching, inability to wear lenses all day, and mucous discharge.
Punctate Keratopathy
Overwear could also cause a problem on top with the cornea, where the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches around the cornea a result of decreased oxygen to the people cells.
The most prospect of a threat to vision will be the corneal ulcer. In this case, bacteria penetrates the surface from the cornea, causing infection that looks like a white spot. If untreated, this infection can penetrate and cause infection inside the eye.
How will we prevent contact problems?
The most critical thing for patients to accomplish is control their contact lens wear. Although many lenses are designed and approved for overnight wear for between 2 and four weeks, most eye doctors recommend nightly removal and cleaning. The single most typical source of contacts related problems is overwear, and a large study showed that overnight wear is fourteen times more prone best contact solution best contact solution to cause ulcers than another risk factor.
Are there safer alternatives to wearing disposable lenses?
Of course, glasses will be the safest way to correct vision without running the potential risk of contact lenses. Since glasses don’t touch the eye area, they cannot cause problems. On the other hand, since they are away from the eye area, the tend not to give vision that’s as sharp as disposable lenses. Rigid or hard disposable lenses are better yet given that they float at first glance from 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, even though it is a surgery. It is much more common for lenses to cause infection, inflammation etc vs. LASIK.
