Everything You Wanted to Know About RGP


While you may be more familiar with soft contact lenses, a second, less familiar kind of contact lenses exists: gas permeable (GP) lenses, also called oxygen permeable lenses.

Actually, hard lenses involve more modern technology than soft lenses, and they last longer, allow greater vision quality, and offer increased durability and deposit resistance. Additionally RGP lenses may also be cheaper in the long term than soft lenses. Of course, its advised to first discuss with your optometrist to decide if RGPs suit your needs. Our optometry staff can assist you in determining whether GP lenses are suitable for you.

Since an RGP is composed of inflexible material, it retains its shape well when you blink, which can allow for clearer vision than the average soft lens. In addition GPs are particularly durable. Though they can break if stepped on, they don’t easily rip like soft lenses. Further, since they consist of materials that don't contain water, proteins and lipids from your tears won't stick to RGPs as easily as they do to soft lenses. Those of you who are extra fussy about vision quality will probably opt for RGPs.

RGPs are also an often preferred option for those that have special considerations such as astigmatism, presbyopia or keratoconus, in which standard contacts may not fit properly or provide enough variety. RGPs are also a better choice for those who need contact lenses after refractive surgery.

If you are considering GP lenses, make sure to first speak to your optometrist to find out if you really are a suitable candidate. You never know…hard lenses could be the perfect match for you!
