How much gas permeable contact lenses cost will depend on your prescription and the brand you choose. If you are not sure if gas permeable lenses are right for you, contact your optician.
Gas permeable contact lenses are rigid lenses that transmit oxygen to the eye. Gas permeable lenses are also known as:
GP lenses
RGP lenses
Oxygen permeable lenses
While all these are rigid lenses, they must not be confused with the old-fashioned hard contact lenses, which are now hardly ever used.
Gas permeable contact lenses let in oxygen, which is essential to eye health and means they can be worn when doing sports and other activities.
