Rigid gas permeable contact lenses

RGP lenses are made of a hard plastic material. They provide very clear crisp vision. They can be a good option if you have very high prescription, astigmatism, or Keratoconus.

RGP materials can be made permeable to gases so are a healthy option for the eye. As they as less flexible than a soft lens, they can sometimes take several weeks for the eye to get used to the sensation of the lens.

The RGP lenses normally last 12-18 months, though sometimes longer with a good care.
