Contact lenses certainly are a very common manner in which patients decide to correct their vision. They have many perks over glasses, but sometimes cause problems too.
Advantages include better vision on account of correction on the surface from the eye, and complete field of vision.
Several problems can take place due to contact lens wear too, so care has to be come to avoid these issues. Many doctors refer their patients to ophthalmolgists for evaluation and treating their lens related problems.
How can contacts damage a persons vision?
Contacts can cause many problems in the eye, but only a number 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 on account of overwear of disposable lenses, either lots of hours per day, or lots of days back to back. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear could also cause a problem on top in the cornea, the place that the top layer of cells are damaged.

The eye doctor sees tiny pinpoint scratches on the cornea due to decreased oxygen to the people cells.
Ulceration
The most possibility of a threat to vision is the corneal ulcer. In this case, bacteria penetrates the surface with the cornea, causing disease that appears as a white spot. If untreated, this infection can penetrate and cause infection inside the attention.
How will we prevent contacts problems?
The most significant thing for patients to do is control their contacts 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 for lens related problems is overwear, and a large study established that overnight wear is fourteen times more likely to cause ulcers than some other risk factor.
Are there safer alternatives to wearing contacts?
Of course, glasses will be the safest method to correct vision without running potential risk of disposable lenses. Since glasses tend not to touch your eye area, they can not lead to further problems. On the other hand, being that they are away from the eyes, the tend not to give vision which is as sharp as contacts. Rigid or hard contact lenses are better yet given that they float on the surface in the eye, effectively smoothing out any rough spots, giving the very best vision.
Recent studies also demonstrate that LASIK has less risks than contacts, even though it is a surgery. It is considerably more common for contacts to cause infection, inflammation etc vs. LASIK.
