Sleeping while wearing contact lenses increases the risk of dangerous infections of the cornea, warns a recent CDC report. In some of the described cases, patients developed corneal ulcers, scarring, or perforation, and most were left with permanent visual impairment.
About one-third of contact lens wearers report sleeping or napping in their lenses. “Sleeping in lenses, whether inadvertently, occasionally, or as part of a prescribed wearing schedule (i.e., extended wear lenses), increases the risk for contact lens-related eye infections six- to eightfold,” according to the CDC.
