Most contact lenses aren’t supposed to be kept on during sleep, but one kind that’s been getting an increasing amount of attention was made to be worn through the night.
In 2002, the FDA approved overnight corneal reshaping method in the form of contact lenses, known as ortho-k or orthokeratology. As you sleep, these lenses flatten the cornea, temporarily correcting nearsightedness so you don’t have to wear glasses or traditional contact lenses the following day. The effect is similar to that of LASIK surgery, minus the permanence. It’s almost like recharging a battery: one night of wear is equal to about one day of corrected vision, so they are intended for nightly use.
Currently, Bausch & Lomb’s Vision Shaping Treatment and Paragon’s Corneal Refractive Therapy are the two brand-name ortho-k lenses approved by the FDA. Both require a fitting by an eye-care professional who has been certified by the respective company. Ask your doctor if you’re a candidate and if he or she has the appropriate brand certification.
