Night lenses, also called orthokeratology or Ortho-K, are contact lenses worn while you sleep. They temporarily reshape the cornea, the clear front surface of your eye, to help improve vision after the lenses are removed.
If you are considering an alternative to daytime glasses or contact lenses, an eye test is the starting point for checking your suitability. Ask your optometrist how Ortho-K could fit your prescription and daily routine.
Ortho-K provides temporary vision correction. Continued lens wear on the schedule prescribed by your optometrist is needed to maintain the effect. Results vary, and some people may still need glasses or contact lenses during the day.
Myopia, or short-sightedness, makes distant objects look blurry. Ortho-K can help slow myopia progression in children; it does not guarantee that progression will stop. Your optometrist can discuss the options and monitoring suited to your child.
Contact lens wear carries risks, including eye infection. Before starting, discuss your suitability, lens cleaning and handling, the wearing schedule and follow-up visits with your optometrist.
