Overnight Vision Correction or Orthokeratology using the Z-CRT design is a new way of correcting vision. These lenses correct your vision while you sleep, so when you wake up and remove them, your vision is clear without the need for any other form of optical correction!

Z-CRT is ideal for anyone who is mild to moderately myopic. Imagine having clear vision all day long without any contact lenses or glasses. Unlike surgical or laser alternatives, Z-CRT is completely reversible so if you stop wearing the lenses your eyes return to normal.

If you are looking into alternatives to eyeglasses and daytime contact lenses, be sure to ask your eye care professional about Z-CRT – it’s a natural alternative to surgery.
