Rigid Gas Permeable (RGP) contact lenses are made of durable plastics that allow oxygen to pass through these lenses. RGPs do not contain water. As such, they offer better eye health in certain circumstances compared to soft contact lenses as they are less likely to collect deposits and contain bacteria. If a RGP is well-maintained, they can last for 2 to 3 years.
