The vast majority of US adolescent contact lens wearers slip up on safety measures known to protect against potentially blinding eye infections, according to a recent CDC report. Even so, their track record on some of those measures is better than that of adult lens wearers. According to the analysis of data from an online survey, an estimated 3.6 million youths aged 12 to 17 years wore contact lenses in 2016. About 85% said they’ve disregarded at least 1 of several recommended contact lens hygiene practices. The most common breaches were not visiting an eye doctor annually, sleeping or swimming while wearing their lenses, and waiting too long to replace lenses or lens cases.
