Safety Tips Every Contact Lens Wearer Should KnowPosted on by
Are you one of the 45 million people in the United States who wear contact lenses to correct your vision? Eye infections related to improper contact lens wear and care are serious and can lead to long-lasting damage, but they are often preventable.
Replace your contact lens case regularly.
A significant number of people who wear contact lenses report not replacing their lens case regularly. Even when cleaned properly (by rubbing and rinsing the case with disinfecting solution), contact lens cases can become contaminated over time with germs that can cause infections when they come into contact with your eyes.
Don’t sleep or nap in your contact lenses.
Sleeping while wearing contact lenses increases the risk of eye infection by 6–8 times. Out of every 10,000 people who sleep in their contact lenses overnight, 18–20 every year will get an infection of microbial keratitis. This disease causes inflammation of the cornea (the clear dome that covers the colored part of the eye), which, in the worse cases, can lead to permanent vision loss or blindness.
Don’t swim or shower in your contact lenses.
The germs found in water can stick to contact lenses and infect your eyes. Wearing contact lenses can put you at increased risk for Acanthamoeba keratitis, a severe type of eye infection caused by a free-living ameba commonly found in water. These infections can be difficult to treat and extremely painful, and in the worst cases they can cause blindness.
Wash your hands with soap and water before touching your contact lenses.
Germs from your hands can be transferred to your contact lenses and the lens case. Some germs that cause eye infections are found in the water, so it is particularly important that you dry your hands before touching your contact lenses. Wash your hands with soap and water and dry them every time you put in and remove your contact lenses.
Visit your eye doctor every year.
Wearing contact lenses increases your risk for eye infections and complications. Therefore, it is important for you to have a yearly eye exam if you wear contact lenses. Sometimes eye doctors may recommend that their patients have more frequent eye exams.
The week of August 21–25, 2017, marks the fourth annual Contact Lens Health Week. This year’s theme, “Healthy habits mean healthy eyes,” will promote healthy contact lens wear and care practices.
