Even though Biotrue contact lenses hold more moisture than other brands and can be worn for up to 16 hours, we do not recommend to sleep with them in. Sleeping while wearing these contacts would result in the top layer of the cornea breaking down, which could result in an infection, possibly scarring the cornea and even leading to permanent vision loss. Sleeping with contacts makes you ten times more likely to develop this infection.
Taking contacts out before bed also helps to air out your corneas. The corneas need to be aired out because they do not have any blood vessels. Instead, the cornea gets oxygen through the air. Disposable contacts are not to be reused because they can tear or break apart. This will lead to damage to the cornea and possibly an infection. We only recommend using the contact lenses following the package's instruction.
We recommend talking to your eye doctor if you have concerns about your eye health and contact use. Your eye doctor can also schedule you for an eye exam if you’re due for one, and let you know if Biotrue contact lenses are right for you.
