To help you understand what Rigid Gas Permeable Lenses are, below are several Frequently Asked Questions and their answers.
What are Rigid Gas Permeable lenses?
Rigid Gas Permeable lenses, otherwise known as RGP, are the newest hard contact lenses. Unlike hard lenses of the past that were made of PMMA (think Plexiglas), RGP lenses are made of an oxygen permeable plastic. A healthy eye needs plenty of oxygen. RGP lenses not only give more oxygen to the eye, they are also more comfortable to wear.
Why are RGP lenses different?
Introduced in the 1980’s, RGP lenses are newer than soft lenses. RGPs have silicone incorporated in their design. Silicone is oxygen permeable, so therefore your eyes will receive plenty of oxygen. In fact, RGPs deliver more oxygen to your eyes than most soft lenses.
