Studies show Orthokeratology or Ortho-K lenses are safe for use by people of many ages, including young children and adults and like any other contact lenses, Ortho-K has the same risk. It is also the most effective optical treatment for myopia control. Ortho-K treatment generally occurs in a controlled safe environment. They are overnight contact lenses that safely corrects your vision when you sleep.  The lenses are worn during sleep, generally up to 8 hours and with your eyes are closed, the lenses are not exposed to outdoor environments like dust.

Ortho-K or night contact lenses, is the next revolution in vision correction, it is a non-surgical, safe and reversible contact lens procedure that gently reshapes the front of your eye to correct people with myopia (short-sightedness) or astigmatism. Many patients with dry eyes also do well with Ortho-K. Since you are wearing the lenses only while sleeping, the closed eye state minimises evaporation loss of tears that can give dry-eye patients improved vision without compromising the ocular surface.
