Gas Permeable Lenses: Do They Make Sense for You?

 

Although you may be most accustomed to soft contact lenses, a second, less familiar kind of contact lens materials exists: rigid gas permeable (RGP) lenses, sometimes referred to oxygen permeable lenses.

In reality, GP lenses involve more modern technology than soft lenses, which are longer-lasting, offer greater vision quality, and offer improved durability and deposit resistance. Further GP lenses can also be cheaper in the long term than soft lenses. Certainly, its best to first discuss with your optometrist to decide if GPs fit your lifestyle. Our optometry practice can help you figure out whether GP lenses are suitable for you.

Because an RGP is made of inflexible material, it retains its form well when you blink, which can afford crisper vision than the typical soft lens. Additionally RGPs are extremely strong. Though they can break if stepped on, they don’t easily rip like soft lenses. Also, since they're composed of materials that don't include water, proteins and lipids from your tears don’t adhere to RGPs as easily as they do to soft lenses. Those of you who are extra fussy about vision quality will probably choose RGPs.

Rigid lenses are also an often preferred option for contact wearers with certain conditions such as astigmatism, presbyopia or keratoconus, in which 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 checking out GP lenses, make sure to first speak to your optometrist to determine if you definitely are a candidate. You never know…hard lenses might be the right answer for you!
