Contact Lenses, Advantages and Disadvantages

Contact lenses really are a quite normal method in which patients decide to correct their vision. They have many perks over glasses, but can lead to further problems too.
Advantages include better vision on account of correction on top of the eye, and finish field of vision.
Several problems can occur on account of contacts wear too, so care have to be come to avoid these complaints. Many doctors refer their patients to ophthalmolgists for evaluation and treatments for their lens related problems.
How can contact lenses damage a person’s eye?
Contacts could cause many problems in a persons vision, 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 as a result of overwear of disposable lenses, either lots of hours daily, or way too many days consecutively. Symptoms include itching, inability to wear lenses for hours on end, and mucous discharge.
Punctate Keratopathy
Overwear may also cause a problem on the surface from the cornea, the location where the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches for the cornea due to decreased oxygen to those cells.
The most potential for a threat to vision could be the corneal ulcer. In this case, bacteria penetrates the surface from the cornea, causing disease that appears as a white spot. If untreated, this infection can penetrate and cause infection inside the eye.
How are we able to prevent contacts problems?
The most significant thing for patients to accomplish is control their contact wear. Although many lenses were created and approved for overnight wear for between 2 and four weeks, most eye doctors recommend nightly removal and cleaning. The single most typical cause of lens related problems is overwear, and a large study demonstrated that overnight wear is fourteen best contact solution

times very likely to cause ulcers than another risk factor.
Are there safer alternatives to wearing disposable lenses?
Of course, glasses would be the safest way to correct vision without running potential risk of contacts. Since glasses tend not to touch the eye area, they won’t create problems. On the other hand, because they are away from the eyes, the don’t give vision that is certainly as sharp as lenses. Rigid or hard disposable lenses are better still since they float on the surface of the eye, effectively smoothing out any rough spots, giving the best vision.
Recent studies also demonstrate that LASIK has less risks than contacts, while it’s a surgery. It is much more common for disposable lenses to cause infection, inflammation etc vs. LASIK.
