Contact lenses can be a quite typical manner in which patients decide to correct their vision. They have several positive aspects over glasses, but tend to 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 has to be taken to avoid these issues. Many doctors refer their patients to ophthalmolgists for evaluation and treatment of their lens related problems.
How can disposable lenses damage a person’s eye?
Contacts could cause many problems in a persons vision, but only a couple of commonly encountered diagnoses could 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 contacts, either lots of hours every day, or lots of days in a row. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear can also lead to a problem on the surface of the cornea, in which the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches for the cornea a result of decreased oxygen to prospects cells.
The most prospect of 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 could we prevent lens problems?
The most important thing for patients to do is control their contacts wear. Although many lenses are created and approved for overnight wear for between 2 and 30 days, most eye doctors recommend nightly removal and cleaning. The single most frequent source of contacts related problems is overwear, as well as a large study showed that overnight wear is fourteen times very likely to cause ulcers than every other risk factor.
Are there safer alternatives to wearing contacts?
Of course, glasses will be the safest way to correct vision without running the risk of contacts. Since glasses do not touch your eyes, they cannot lead to further problems. On the other hand, because they are away from the eyes, the don’t give vision that is certainly as sharp as contact lenses. Rigid or hard contacts are best best contact solution
best contact solution for sensitive eyes
of all simply because they float on the surface of the eye, effectively smoothing out any rough spots, giving the most effective vision.
Recent studies also demonstrate that LASIK has less risks than lenses, while it’s a surgery. It is considerably more common for contacts to cause infection, inflammation etc vs. LASIK.
