Hard Contact Lens

Hard contact lens is also  called RGP (rigid gas permeable).   Its popularity has dropped  since the invention of soft contact lenses.   However it is a good option for people who has dry eyes, high astigmatism, and someone who is used to the clear vision provided by RGP.   Sometiems it is the only option for people who have compromised corneal integrity (please refer to Special Contact Lens).
