What are RGP contact lenses?
According to an article submitted to allaboutvision.com, RGP contact lenses, or Rigid Gas Permeable lenses, transmit more oxygen to the wearer’s eye. Unlike the “hard contacts” of the 1970s, RGPs are made of polymers that make the contacts permeable to oxygen. These lenses can be worn for a number of ailments, including astigmatism and presbyopia.FeaturesGas Permeable (GP) contact lenses are also known as oxygen permeable lenses and Rigid Gas Permeable lenses (RGPs). Compared to traditional soft contact lenses, gas permeable lenses are proven to transmit more oxygen to the wearer’s eyes.BenefitsGas Permeable lenses are made of a stiff material, so when a wearer blinks, the lenses retain their shape, which provides better vision. GPs are not easily torn, as most soft contact lenses are. They can last for years unless a prescription change is needed.DownsidesFull-time lens wear can prohibit “spectacle blur,” or blurry vision, which can occur when the wearer takes his lenses out.
