Lack of Proper Contact Lens Care Can Cause Corneal Ulcers

The cases of corneal ulcers are growing. Last year there were about 30,000 cases diagnosed. This is a condition that can cause blindness. One of the primary reasons for this increase is due to improper care of contact lens.

In a recent study almost one in 13 contact lens wearers had abrasions on the cornea severe enough to lead to infections or other problems. Mild abrasions happens to just about all people, whether they wear contacts or not. But the chances are increased for contact lens wearers if they don't clean and replace their lenses on a regular basis.

Like our skin, the surface of the cornea regenerates new cells. Old cells are slough away in order to make room for new cells. But often too many cells are shed leaving a gateway for bacteria, viruses, and other microorganisms.

One other major cause is sleeping with your contact lens. Ophthalmologist Shahzad Mian says, "It is best not to ever sleep in the contact lenses."

Mian adds, "Extended-wear lenses do not imply that patients should be sleeping in them."
Mian cites the maintenance of contact lenses, specifically how you clean and store them, is just as important.

"Water should never be used, because tap water can be contaminated with bacteria or parasites, which can lead to very serious problems."

The same goes for using saliva to wet lenses. Also, clean your contact lens cases regularly with hot water and replace them about every three months.

Colored Contacts

Concerns have also been raised about the perils - infection and blindness - of wearing non-prescription colored contact lenses and their inadequate care.

Colored contact lenses have become extremely popular. Woman in particular feel that the colored contact lenses highlight their eyes and make them more appealing. Also young people are usings a variety of "crazy contacts" and theatrical contacts. But the wearers need to be aware of the risks of serious infection and in some cases blindness. The problem stems from the unregulated sale of lenses, which are sold without an eye doctor's prescription.

It is recommended that those who opt for colored contact lenses for cosmetic reasons should seek the advice of ophthalmalogists to ensure that they are suitable candidates for contact lenses. In the process they should learn the proper methods of care and beware of the risks that can result from poor maintenance. It is suggested that the lenses should be removed each evening, even if they are disposable lenses.
