Although you may be more accustomed to soft contact lenses, another lesser-known brand of contact lenses exists: gas permeable (GP) lenses, sometimes known as oxygen permeable lenses.
In truth, hard lenses involve newer technology than soft contacts, and they last longer, are often more successful in improving vision, and provide improved durability and resistance to protein deposits. Further they may also be cheaper in the long run than soft lenses. Certainly, its best to first consult with your eye doctor to determine if RGPs suit your needs. Our optometry office can assist you in ascertaining if GP lenses are suitable for you.
Because an RGP is composed of inflexible material, it does a good job of retaining its shape when you blink, which tends to allow for crisper vision than the typical soft lens. Furthermore GPs are extremely durable. Though they will break if stepped on, they don’t easily rip like soft lenses. Also, because they're made of substances that don't contain water, proteins or lipids from your tears don’t stick to GPs as readily as they will to soft lenses. People that are especially particular about quality of vision will most likely opt for RGPs.
GPs are also an often preferred option for those with special considerations such as astigmatism, presbyopia or keratoconus, in which standard contacts may not produce the desired visual acuity. RGPs are also preferable for contact users post refractive surgery.
If you are considering RGP lenses, make sure to first speak to your optometrist to find out if you truly are a candidate. Who knows…hard lenses might be the right match for you!
