Contact Lenses, Advantages and Disadvantages

Contact lenses are a quite normal manner in which patients choose to correct their vision. They have several positive aspects over glasses, but sometimes make trouble too.
Advantages include better vision due to correction on top with the eye, and handle field of vision.
Several problems can occur on account of contact lens wear too, so care should be come to avoid these issues. Many doctors refer their patients to ophthalmolgists for evaluation and treating their lens related problems.
How can disposable lenses damage a person’s eye?
Contacts may cause many problems in the eye, but only a number 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 because of overwear of disposable lenses, either a lot of hours daily, or a lot of days uninterruptedly. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear may also cause a problem on top of 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 people cells.
The most possibility of a threat to vision will be the corneal ulcer. In this case, bacteria penetrates the surface of the cornea, causing contamination that looks like a white spot. If untreated, this infection can penetrate and cause infection inside the attention.
How could we prevent contacts problems?
The most significant thing for patients to accomplish is control their contact lens wear. Although many lenses were created and approved for overnight wear for between 2 and 30 days, most eye doctors recommend nightly removal and cleaning. The single most popular reason for contacts related problems is overwear, and a large study demonstrated 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 include the safest method to correct vision without running the potential risk of contacts. Since glasses usually do not touch the eye area, they can not create problems. On the other hand, since they are away from the eye area, the usually do not give vision that’s as sharp as contacts. Rigid or hard disposable lenses are best contact solution
best contact solution for sensitive eyes
even better simply because they float on the surface in the eye, effectively smoothing out any rough spots, giving the most effective vision.
Recent studies also demonstrate that LASIK has less risks than disposable lenses, this specific a surgery. It is much more common for contacts to cause infection, inflammation etc vs. LASIK.
