Rigid-gas-permeable corrective contact lenses for daily wear are ophthalmic devices designed to sit directly on the cornea to correct vision problems such as nearsightedness, farsightedness, astigmatism, and age-related focusing difficulties. They are made from firm, oxygen-permeable materials that allow oxygen to reach the eye while maintaining shape and clarity, and are intended to be removed each night before sleep.
These lenses are reusable devices that can last for several years with proper care and are regulated as medical devices based on their design, materials, and intended use. Regulatory requirements focus on safety, performance, and biocompatibility, with classification depending on the jurisdiction and specific risk profile of the device.
