Rigid Gas Permeable Lenses, often called RGP lenses, are a type of contact lens made from durable plastic that allows oxygen to pass through to the eye. Unlike soft lenses, RGP lenses maintain their shape on the eye, providing clear vision and correcting various vision problems, including astigmatism and myopia. These lenses are known for their longevity and can last for years with proper care. They are also less likely to cause eye infections compared to soft lenses, as they do not retain as much moisture. Regular cleaning and proper fitting by an eye care professional are essential for comfort and effectiveness.
