Gas Permeable Lenses: Are You a Candidate?


While you may be most accustomed to soft contact lenses, another less familiar brand of contact lens materials exists: rigid gas permeable (RGP) lenses, sometimes called oxygen permeable lenses.

In truth, hard lenses involve newer technology than soft lenses, which are longer-lasting, offer greater vision quality, and offer better durability. Additionally they can also be less expensive in the long term than soft lenses. Of course, its advised to first discuss with your optometrist to decide whether hard lenses fit your lifestyle. Our optometry office can help you determine if hard lenses are suitable for you.

Because an RGP is made of inflexible material, it retains its shape well when you blink, which can allow for sharper vision than the average soft lens. In addition GPs are particularly strong. Although they will break if stepped on, they don’t tear easily like soft lenses. Also, because they consist of materials that don't include water, proteins and lipids from your tears don’t adhere to GPs as easily as they do to soft lenses. People that are extra particular about vision quality will probably opt for RGPs.

GPs are also an often preferred option for contact wearers with special considerations such as astigmatism, presbyopia or keratoconus, where soft lenses may not fit comfortably or offer enough variety. RGPs are also preferable for those who need contact lenses after refractive surgery.

If you're looking into RGP lenses, be sure to first speak to your optometrist to ascertain if you definitely are a suitable candidate. You never know…hard lenses might be the perfect solution for you!
