Why Gas Permeable Lenses Might be Right for You



Although soft contact lenses are most common, another less familiar type of contact lens materials exists: rigid gas permeable (RGP) lenses, also called oxygen permeable lenses.

Actually, GP lenses involve newer technology than soft lenses, and they last longer, offer better vision quality, and provide better resilience. Additionally RGP lenses can also be cheaper in the long run than soft lenses. Certainly, its best to first discuss with an optometrist to decide whether RGPs fit your needs. Our optometry practice can assist you in ascertaining if you’re a candidate for hard lenses.

Because an RGP is composed of stiff material, it does a great job of retaining its shape when you blink, which can allow for crisper vision than the typical soft lens. Additionally GPs are particularly strong. Though they can break if stepped on, they don’t easily rip like soft lenses. Further, because they consist of substances that don't contain water, proteins or lipids from your tears won't stick to GPs as easily as they will to soft lenses. Those of you who are extra fussy about quality of vision will probably choose RGPs.

GPs are also sometimes preferred for contact wearers with certain conditions such as astigmatism, presbyopia or keratoconus, in which soft lenses may not produce the desired visual acuity. RGPs are also preferable for contact users after refractive surgery.

When checking out GP lenses, make sure to first ask your eye doctor to verify if you truly are a suitable candidate. Who knows…hard lenses might be the perfect solution for you!
