Many Engaging In Contact Lens Behavior That Could Cause Infection

Almost all of the 41 million estimated contact lens wearers in the United States may be engaging in at least one behavior known to increase their risk of eye infections, according to a report published by the Centers for Disease Control and Prevention. 

Nearly one-third of contact lens wearers who participated in a national survey reported seeking treatment for red or painful eyes related to wearing contact lenses.

More than 99% of survey respondents reported at least one risky behavior. The majority of wearers reported:

  • Keeping their contact lens cases for longer than recommended (82.3%);
  • “Topping off” solution in the case—adding new solution to the existing solution instead of emptying the case out fully before adding new solution (55.1 %); or
  • Wearing their lenses while sleeping (50.2%).

Each of these behaviors has been reported in previous studies to raise the risk of eye infections by five times or more.

An online survey was administered to a sample of contact lens wearers to determine how often contact lens wearers engaged in behaviors that could put them at risk for an eye infection. CDC collaborated with the Contact Lens Assessment in Youth (CLAY) group, a multi-university group of researchers, to conduct the survey. 

A separate survey was used to estimate the number of contact lens wearers – about 41 million adults. Taken together, the survey results indicate that millions of Americans could be at risk for serious eye infections because of poor contact lens hygiene behaviors.

“Good vision contributes to overall well-being and independence for people of all ages, so it's important not to cut corners on healthy contact lens wear and care,” says CDC Medical Epidemiologist Jennifer Cope, MD, MPH. "We are finding that many wearers are unclear about how to properly wear and care for contact lenses."

Aug. 24 through 28, 2015, marks the second annual Contact Lens Health Week.
