What are rigid gas permeable contact lenses?
Rigid gas permeable contact lenses are not as pliable as soft lenses, but not as inflexible as hard contact lenses. This property stems from the incorporation of silicone into the plastic. Silicone makes the lens much more flexible, whilst allowing oxygen to permeate through. Although slightly harder to get used to than soft lenses, RGP’s are much more durable and easier to clean.
