Ortho-keratology: Crt or ortho-k contact lenses act as all contact lenses do, gently shaping the cornea so that it focuses distant objects better. Unlike regular contacts, the effects of ortho-k can last up to a day or so after removing them. They are worn at night while sleeping and taken off during the day. As with all contact lenses, crt lenses can cause glare at night, so be careful driving.
