Although you may be more familiar with soft contact lenses, a second, less familiar type of contact lens materials exists: gas permeable (GP) lenses, sometimes referred to oxygen permeable lenses.
In truth, RGP lenses are a more modern technology than soft lenses, and they last longer, allow finer vision quality, and provide increased resilience. Additionally RGP lenses may also be less expensive in the long term than soft lenses. Of course, its advised to first discuss with an eye care practitioner to determine if GPs fit your needs. Our optometry staff can assist you in ascertaining if you’re a candidate for GP lenses.
Because an RGP is made of inflexible material, it maintains its form well when you blink, which tends to afford sharper vision than the typical soft lens. Additionally RGPs are especially long-lasting. Though they will break if stepped on, they don’t tear easily like soft lenses. Also, because they're made of materials that don't contain water, proteins or lipids from your tears won't adhere to RGPs as easily as they do to soft lenses. Those of you who are extra particular about quality of vision will most likely choose GPs.
RGPs are also a good choice for those with certain conditions such as astigmatism, presbyopia or keratoconus, where standard contacts may not produce the desired visual acuity. RGPs are also suitable for contact users after refractive surgery.
If you're looking into GP lenses, be sure to first speak to your eye care practitioner to verify if you really are a suitable candidate. Who knows…hard lenses could be the perfect solution for you!
