Gas permeable (GP) contact lenses are also known as rigid gas permeables (RGP’s).Although today’s gas permeable lenses are made of a rigid material that is not flexible, they differ greatly from the original hard lenses of yesteryear.Hard contact lenses made of polymethylmethacrylate (PMMA), were introduced in the 1930’s.rthokeratology is the process of using special gas permeable lenses to temporarily correct/reduce myopia by reshaping the cornea. An eye health professional may refer to this process as corneal reshaping (CR) as corneal refractive therapy or vision shaping.

They are often referred to as oxygen permeable lenses and are available in daily wear and extended wear options. Advantages. 1  Clear, crisp vision. Gas permeable contact lenses are also called RGP (Rigid Gas Permeable) contact lenses, and oxygen permeable lenses.GP designs are differentiated primarily by size.hey are large (15 to 17 mm) in diameter to cover most of the eye’s surface, and are primarily used to manage complex eye conditions. Gas permeable contact lenses are generally worn during waking hours, although some materials are approved—but infrequently prescribed—for overnight wear. In contrast, most soft lenses provide relatively instant comfort. One disadvantage is the size of a gas permeable contact lens compared to a soft lens. Most GP lenses are much smaller and are designed to move on the eye with each blink.hey are large (15 to 17 mm) in diameter to cover most of the eye’s surface, and are primarily used to manage complex eye conditions.
