Rigid gas permeable lenses are rigid contact lenses 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.
Rigid lenses are able to replace the natural shape of the cornea with a new refracting surface. This means that a regular (spherical) rigid contact lens can provide good level of vision in people who have astigmatism or distorted corneal shapes as with keratoconus. However, they require a period of adaptation before full comfort is achieved.[1]
Removal of Rigid Gas Permeable (RGP) Contact Lenses:
Removing contact lens incorrectly could result in damage to the lens and injury to the eye. So care must be taken while removing contact lenses. Rigid contact lenses can be removed by pulling the outer corner of the eye towards the ear. The contact lens simply gets ejected on blinking the eye.The other hand should be kept ready to catch the falling lens.[2]
