2. Rigid gas permeable lens - Wikipedia

   en.wikipedia.org/wiki/Rigid_gas_permeable_lens

   A rigid gas-permeable lens, also known as an RGP lens, GP lens, or colloquially, a hard contact lens, is a rigid contact lens made of oxygen -permeable polymers. Initially developed in the late 1970s, and through the 1980s and 1990s, they were an improvement over prior 'hard' lenses that restricted oxygen transmission to the eye.
