Keep your contact lenses out of the swimming pool

Swimming KidSummer is here in full force. If the sweltering heat hasn’t driven you to the pool yet, it’s only a matter of time before a friend or child drags you along. In fact, according to a Red Cross survey, 94% of parents expect their child to engage in some sort of water related activity during the summer season.1

Everyone knows you need to wear sunblock to protect your skin. But, has anyone told you to remove your daytime contact lenses to protect your eyes? Contact lenses are extremely safe, but there can be complications associated with improper use. As harmless as it may seem, swimming with contact lenses may present a significant risk factor for the development of a severe, vision threatening eye infection known as microbial keratitis2.

Risk of Microbial Keratitis Swimming in Contact Lenses

Microbial Keratitis is an infection of the cornea that can occur as a result of bacteria or other micro-organisms infiltrating an open wound and being allowed to spread farther into the eye.2 The eye’s built-in epithelial barrier and immune response combats bacteria every day. The body’s natural tear flow and blink cycle are excellent ways to flush these bacteria out of the eye before an infection can occur.3

When any contact lens wearer exposes his or her eye to any non-sterile liquid there is always a chance that the liquid will trap a small number of bacteria underneath the lens preventing the tear flow and blink cycle from flushing out the foreign body. If the individual has even a microscopic abrasion on the eye, the bacteria can infiltrate the open wound and begin to spread.3 This is precisely why swimming in contact lenses may expose individuals to higher risk of these infections.4

Special Reminder to Keep Your Lenses Clean and Don’t Rinse in TAP Water

Remember how your eye care professional told you over-and-over to never wash your contact lenses in sink or tap water? The sterile cleaning solution is there for a reason. When an individual dives into a pool of water without removing their contact lenses first, they are exposing themselves to the same risks as those that clean their contacts with non-sterilized water.3
