The Benefits of Gas Permeable Lenses

While soft contact lenses are most common, a second, lesser-known brand of contact lens materials exists: gas permeable (GP) lenses, sometimes known as oxygen permeable lenses.

In truth, RGP lenses involve more modern technology than soft lenses, and they are longer-lasting, offer finer vision quality, and offer increased resilience. Additionally GP lenses may also be cheaper in the long run than soft lenses. Of course, it's best to first consult with your optometrist to decide if RGP's suit your needs. Our optometry practice can assist you in ascertaining if you're a candidate for RGP lenses.

Because a GP lens is composed of inflexible material, it does a good job of maintaining its shape when you blink, which can provide crisper vision than the typical soft lens. In addition RGP's are extremely long-lasting. Though they will crack if stepped on, they don't tear easily like soft lenses. Further, because they're made of materials that don't contain water, proteins or lipids from your tears won't stick to RGP's as easily as they will to soft lenses. Those of you who are especially fussy about quality of vision will most likely choose gas permeable lenses.

RGP's are also a good choice for people with certain conditions such as astigmatism, presbyopia or keratoconus, in which soft lenses may not fit comfortably or provide enough variety. GP's are also preferable for those who need contact lenses after refractive surgery.

If you are considering hard lenses, be sure to first ask your eye doctor to determine if you definitely are a candidate. Who knows… hard lenses might be the perfect answer for you!
