Summer & your eyes: Swimming pools

Yay – Summer is officially here!

School is out and we finally get to spend some serious time in the pool. But before you jump in, here are a few quick safety tips for you and your eyes:

  • The pH of our eyes is 7.2, so can you guess what the recommended pH is for your pool? (hint: it’s 7.2!) Remember to check the pH levels in your pool at least once or twice a week and try to keep it in the range of 7.0-7.6.
  • Chemical conjunctivitis or red eyes can occur due to chlorine exposure in swimming pools. Having a little after a day in the pool is okay, but if it persists into the next day or if it seems to be getting worse, call your optometrist and ask to have your eyes checked that same day.
  • As a general rule, contact lenses should never be worn in the pool. Doing so puts you at risk for a variety of possible infections, including a fungal infection called Fusarium keratitis that is difficult to treat and can lead to permanent blindness. (The only exclusion to this rule is for my daily disposable contact lens patients under the strict condition that their contacts are thrown out as soon as they leave the pool.)
  • Prescription goggles are available and can be fairly inexpensive! If you rely on your glasses to see, talk to your optometrist about prescription goggles for use in the pool.
  • And if you plan to be hanging out around the pool this summer, remember that sunglasses are just as important for protecting your eyes as sunblock is for protecting your skin. Make sure yours have UVA and UVB protection.

Have safe and fun summer!
