Although soft contacts are most common, a second, less familiar kind of contact lens materials exists: rigid gas permeable (RGP) lenses, also referred to oxygen permeable lenses.
In reality, hard lenses involve newer technology than soft lenses, which are longer-lasting, can be more successful in improving vision, and offer increased durability. Additionally GP lenses may also be cheaper in the long term than soft lenses. Certainly, you need to first discuss with an eye care practitioner to determine whether RGPs suit your needs. Our optometry office can assist you in ascertaining whether GP lenses are right for you.
Because a GP is constructed from inflexible material, it maintains its form well when you blink, which tends to allow for crisper vision than the typical soft lens. In addition GPs are particularly long-lasting. Although they can break if stepped on, they don’t tear easily like soft lenses. Further, because they consist of substances that don’t contain water, proteins and lipids from your tears don’t stick to RGPs as easily as they do to soft lenses. Those of you who are extra particular about vision quality will most likely opt for RGPs.
RGPs are also an often preferred option for those that have certain conditions such as astigmatism, presbyopia or keratoconus, in which soft lenses may not fit comfortably or offer enough variety. GPs are also preferable for contact users after refractive surgery.
When looking into RGP lenses, be sure to first ask your eye doctor to verify if you definitely are a candidate. You never know…hard lenses might be the perfect answer for you!
