Contact Lenses, Advantages and Disadvantages

Contact lenses can be a quite normal manner in which patients choose to correct their vision. They have several positive aspects over glasses, but tend to create problems too.
Advantages include better vision on account of correction on top of the eye, and finish field of vision.
Several problems can occur as a result of contacts wear too, so care should be delivered to avoid these problems. Many doctors refer their patients to ophthalmolgists for evaluation and treatments for their lens related problems.
How can contact lenses damage the eye?
Contacts can 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 would be the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs due to overwear of disposable lenses, either a lot of hours daily, or lots of days in a row. Symptoms include itching, inability to wear lenses throughout the day, and mucous discharge.
Punctate Keratopathy
Overwear can also cause a problem on top in the cornea, where the top layer of cells are damaged. best contact solution

The eye doctor sees tiny pinpoint scratches about the cornea due to decreased oxygen to prospects cells.
Ulceration
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 looks like a white spot. If untreated, this infection can penetrate and cause infection inside the eye.
How will we prevent contact lens problems?
The most critical thing for patients to accomplish 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 common reason behind lens related problems is overwear, along with a large study indicated that overnight wear is fourteen times prone to cause ulcers than another risk factor.
Are there safer choices to wearing contact lenses?
Of course, glasses would be the safest strategy to correct vision without running potential risk of disposable lenses. Since glasses tend not to touch the eyes, they can’t lead to further problems. On the other hand, because they are away from the eye area, the do not give vision that is as sharp as disposable lenses. Rigid or hard disposable lenses are best of all simply because they float on top of the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also demonstrate that LASIK has less risks than lenses, this specific a surgery. It is considerably more common for lenses to cause infection, inflammation etc vs. LASIK.
