Gas Permeable Lenses: Do They Make Sense for You?

 

While soft contacts are most common, another lesser-known kind of contact lens materials exists: gas permeable (GP) lenses, sometimes referred to oxygen permeable lenses.

In reality, RGP lenses involve newer technology than soft lenses, and they last longer, offer greater vision quality, and offer better durability. Additionally they can also be less expensive in the long run than soft lenses. Of course, you need to first consult with your eye care practitioner to determine whether RGPs suit your lifestyle. Our optometry office can help you figure out whether you’re a candidate for hard lenses.

Because a GP is constructed from stiff material, it retains its shape well when you blink, which can allow for sharper vision than the average soft lens. Furthermore RGPs are especially durable. Though they can crack if stepped on, they don’t easily rip like soft lenses. Further, because they're made of substances that don't include water, proteins or lipids from your tears won't stick to GPs as readily as they do to soft lenses. Those of you who are extra particular about vision quality will probably opt for RGPs.

GPs are also an often preferred option for those with special considerations such as astigmatism, presbyopia or keratoconus, where standard contacts may not fit properly or provide enough variety. GPs are also preferable for contact users after refractive surgery.

If you are checking out hard lenses, be sure to first ask your eye care practitioner to verify if you truly are a suitable candidate. Who knows…hard lenses might be the perfect answer for you!
