As with any doctor’s prescription, contact lens prescriptions and directions should be followed accurately and never abused. Improper maintenance, wearing expired prescription contacts, or wearing contact lenses beyond their recommended use can all contribute to eye infection, disease, and in severe cases, blindness.
It's very important to pay attention to the expiration date and recommended use period of your contact lenses. If you are unsure of either, consult your eye doctor or the business where you purchased your contact lenses.
The possible eye ailments linked to over-wearing contact lenses are various. Here are a few examples of some common problems associated with contact lens abuse.
More commonly known as "pink eye," conjunctivitis is an eye infection which symptoms include eye itching, redness, increased lens awareness, discharge, and blurred vision. Of the many causes. protein buildup on the contact lens is among the most common, and often, results in an allergic reaction. Lenses that are worn beyond their recommended use can build up heavy deposits of protein, which can cause numerous problems in addition to an allergic reaction.
Contact lens overuse can also lead to swelling of the cornea, called corneal edema. Corneal edema happens when fluid accumulation within the cornea creates swelling. The fluid accumulation can result from many catalysts, including lack of oxygen to the eye from contact overuse. Symptoms of corneal edema include blurred vision and seeing rainbows or halos around lights. This infection can be treated and cured by treatments and/or surgery.
Disposable contacts have an effective date for a reason: once past their expiration or recommended usage date, the lenses start to deteriorate and are no longer suitable for daily use. Overused contacts can let in small particles of dust or dirt, which comes between the contact and the eye. When this happens, the particles can scratch the surface of the eye and create corneal abrasion. When this abrasion is infected, it can cause a corneal ulcer.
A corneal ulcer is one of the most severe types of eye damage that can result from contact lens overuse. Symptoms include eye redness, pain, discharge, blurry vision, and swollen eyelids. Its long-term effects, if untreated, include corneal scarring and corneal perforation. If you think you might have a corneal ulcer, remove your contact lens immediately and consult a physician.
You wouldn’t buy, let alone drink, milk beyond the sell-by date. You know it’s unsafe to run worn-tires on your car. The same thing applies to your contact lenses. Using contacts beyond their recommended usage can result in a whole host of undesired, debilitating eye ailments. If you need new lenses but don’t have the time to order them, wear your glasses. If you don’t have a backup pair, get some. Your eyes are far too precious to let irresponsibility be the cause of serious harm.
