While you may be more accustomed to soft contact lenses, a second, lesser-known brand of contact lens materials exists: gas permeable (GP) contact lenses, sometimes known as oxygen permeable lenses.
In truth, GP lenses involve more modern technology than soft contacts, which are longer-lasting, are often more successful in improving vision, and offer improved durability and resistance to protein deposits. Additionally GP lenses can also be cheaper in the long term than soft lenses. Of course, its best to first discuss with your eye doctor to determine whether GPs fit your lifestyle. Our optometry office can assist you in ascertaining whether you’re a candidate for GP lenses.
Since an RGP is composed of inflexible material, it does a great job of maintaining its form when you blink, which tends to afford clearer vision than the average soft lens. Furthermore RGPs are particularly durable. Although they can crack if stepped on, they don’t easily rip like soft lenses. Further, because they consist of materials that don't contain water, proteins or lipids from your tears won't stick to GPs as easily as they do to soft lenses. Those of you who are extra particular about vision quality will probably opt for RGPs.
RGPs are also an often preferred option for people that have special considerations such as astigmatism, presbyopia or keratoconus, in which standard contacts may not produce the desired visual acuity. RGPs are also a better choice for contact users post refractive surgery.
When thinking about GP lenses, be sure to first speak to your eye doctor to ascertain if you definitely are a candidate. Who knows…hard lenses might be the perfect solution for you!
