Contact Lenses, Advantages and Disadvantages

Contact lenses can be a common manner in which patients decide to correct their vision. They have several advantages over glasses, but could lead to further problems too.
Advantages include better vision because of correction on the outside of the eye, and handle field of vision.
Several problems can take place because of contact wear too, so care have to be delivered to avoid these complaints. 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 might cause many problems in a person’s eye, but only a couple of commonly encountered diagnoses can cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration are the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs because of overwear of contacts, either lots of hours each day, or lots of days in a row. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear may 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 prospects cells.
Ulceration
The most possibility of a threat to vision may be the corneal ulcer. In this case, bacteria penetrates the surface of the cornea, causing an infection that looks like a white

spot. If untreated, this infection can penetrate and cause infection inside a person’s eye.
How will we prevent contact problems?
The most important thing for patients to perform is control their contacts wear. Although many lenses were created and approved for overnight wear for between 2 and a month, most eye doctors recommend nightly removal and cleaning. The single most frequent reason behind contact lens related problems is overwear, as well as a large study established that overnight wear is fourteen times more likely to cause ulcers than another risk factor.
Are there safer alternatives to wearing lenses?
Of course, glasses include the safest way to correct vision without running potential risk of contacts. Since glasses usually do not touch your eye area, they won’t cause problems. On the other hand, because they are away from your eye area, the do not give vision that is certainly as sharp as contact lenses. Rigid or hard contacts are better yet given that they float on top from the eye, effectively smoothing out any rough spots, giving the top vision.
Recent studies also demonstrate that LASIK has less risks than disposable lenses, this specific a surgery. It is considerably more common for contacts to cause infection, inflammation etc vs. LASIK.
