Contact Lenses, Advantages and Disadvantages

Contact lenses can be a very common way that patients choose to correct their vision. They have several advantages over glasses, but sometimes create problems too.
Advantages include better vision because of correction on the outside of the eye, and finished field of vision.
Several problems can happen due to contact lens wear too, so care must be delivered to avoid these issues. Many doctors refer their patients to ophthalmolgists for evaluation and treatment of their lens related problems.
How can lenses damage a person’s eye?
Contacts can cause many problems in a persons vision, but only a number of commonly encountered diagnoses might cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration are the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs on account of overwear of contact lenses, either way too many hours every day, or a lot of days back to back. Symptoms include best contact solution
best contact solution for sensitive eyes
itching, inability to wear lenses all day, and mucous discharge.
Punctate Keratopathy
Overwear may also result in a problem on the outside with the cornea, the place that the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches on the cornea a result of decreased oxygen to those cells.
Ulceration
The most possibility of a threat to vision will be the corneal ulcer. In this case, bacteria penetrates the surface from the cornea, causing contamination that seems as a white spot. If untreated, this infection can penetrate and cause infection inside a persons vision.
How can we prevent contacts problems?
The most significant thing for patients to do is control their contact wear. Although many lenses are designed and approved for overnight wear for between 2 and a month, most eye doctors recommend nightly removal and cleaning. The single most common reason behind contacts related problems is overwear, and a large study demonstrated that overnight wear is fourteen times more likely to cause ulcers than every other risk factor.
Are there safer choices to wearing disposable lenses?
Of course, glasses would be the safest method to correct vision without running the potential risk of contacts. Since glasses tend not to touch the eye area, they cannot create problems. On the other hand, since they will be away from the eyes, the don’t give vision that’s as sharp as contacts. Rigid or hard lenses are better still simply because they float on the surface of the eye, effectively smoothing out any rough spots, giving the top vision.
Recent studies also reveal that LASIK has less risks than contact lenses, this specific a surgery. It is much more common for contacts to cause infection, inflammation etc vs. LASIK.
