Although you may be most familiar with soft contact lenses, another less familiar brand of contact lenses exists: gas permeable (GP) contact lenses, sometimes known as oxygen permeable lenses.
In reality, GP lenses are a newer technology than soft contacts, and they last longer, can be more successful in improving vision, and offer enhanced deposit resistance. Additionally RGP lenses may also be less expensive in the long term than soft lenses. Of course, its best to first discuss with your optometrist to decide if RGPs fit your lifestyle. Our optometry staff can assist you in ascertaining if GP lenses are right for you.
Since a GP is composed of inflexible material, it retains its shape well when you blink, which tends to allow for crisper vision than the typical soft lens. In addition GPs are particularly long-lasting. Though they can break if stepped on, they don’t easily rip like soft lenses. Further, since they consist of materials that don't include water, proteins and lipids from your tears won't adhere to GPs as readily as they do to soft lenses. People that are extra particular about vision quality will probably opt for GPs.
Rigid lenses are also sometimes preferred for contact wearers with certain conditions such as astigmatism, presbyopia or keratoconus, where standard contacts may not fit comfortably or provide enough variety. RGPs are also preferable for those who need contact lenses after refractive surgery.
If you are checking out hard lenses, be sure to first speak to your eye doctor to find out if you definitely are a candidate. Who knows…hard lenses might be the right solution for you!
