Contact lenses are use either for medical or cosmetic purpose. In terms of medical they are devices worn directly on the cornea of the eye. Like eyeglasses, contact lenses help to correct refractive errors and perform this function by subtracting or adding focusing power to the eye’s cornea and lens.“Contact lenses are a safe and effective form of vision correction when worn and cared for as recommended,” said by director of the CDC’s Healthy Water Program, Michael Beach, PhD, in a press release about the survey. “However, improper wear and care of contact lenses can cause eye infections that sometimes lead to serious, long-term damage.” Proper contact lens hygiene is necessary to avoid any type of eye infection.
More than 1,000 cases of contact lens-related infections reported to a federal database over the last decade,examined by the U.S. Centers for Disease Control and Prevention (CDC) and found that nearly 1 in 5 of those infections resulted in eye damage—either a scarred cornea,the need for a corneal transplant or a decline in vision.But by simply using your contacts the way you’re supposed to, you can protect your eyes. About 25% of the reported cases involved behaviors known to put a person at greater risk of eye infection.
Here are six common mistakes you might be making with your contact lenses, and what to do instead.
Sleep with your contacts:
The antibodies and enzymes that protect the surface of your eyes require oxygen to fight off germs. The air supply is reduced,when your eyes are closed at night;wear your contacts to bed and there’s even less oxygen available.
Handling of contact lenses:
To avoid transferring dirt,oil and bacteria to your eyes, clean your hands before you clean your contacts.
You’re not rubbing your contacts:
Give your lenses a rub in your cleaned palm to remove germs and protein buildup. Even if you use a contact solution, it’s still a good idea.
You don’t change your solution daily:
You should empty the contact lens case after putting in your contacts, rinse it with fresh saline, dry it with a fresh, clean tissue and store it upside down on a clean tissue (with the lids off), until you are ready to use it again. According to an assistant professor of ophthalmology Reena Garg, MD,at the Icahn School of Medicine in New York City, told Health in a prior interview, “That’s like doing your laundry in dirty water.” You should always use fresh multipurpose saline solution (never water!), and don’t mix old saline solution with new in your contact case,according to CDC.
You shower and swim with wearing your contacts:
Parasites and Bacteria in water can get caught under your lenses. To avoid a rare but potentially blinding infection caused by an amoeba called Acanthamoeba, as well as other types of infections, CDC advises keeping your lenses away from water (including pool water). Use prescription goggles, if you are a swimmer.
You leave your lenses in too long:
Using your glasses instead of lenses, when you’re at home and on weekends.In an interview with Health, Berkeley, Michigan-based ophthalmologist Steven Shanbom, MD recommended that lens wearers keep their contacts in for no more than 12-14 hours a day.
