While you may be more familiar with soft contact lenses, another less familiar brand of contact lenses exists: rigid gas permeable (RGP) contact lenses, also referred to oxygen permeable lenses.
In truth, GP lenses involve newer technology than soft lenses, which last longer, offer greater vision quality, and provide increased durability. Further RGP lenses may also be less expensive in the long run than soft lenses. Certainly, its best to first consult with an optometrist to decide if RGPs suit your needs. Our optometry office can assist you in determining if you'd be a fit for GP lenses.
Because a GP is constructed from inflexible material, it does a good job of maintaining its form when you blink, which can provide crisper vision than the average soft lens. Additionally RGPs are extremely long-lasting. Though they can crack if stepped on, they don’t tear easily like soft lenses. Further, because they're composed of materials that don't include water, proteins or lipids from your tears don’t adhere to GPs as easily as they will to soft lenses. People that are especially particular about vision quality will most likely choose RGPs.
Rigid lenses are also a good choice for people with certain conditions such as astigmatism, presbyopia or keratoconus, where standard contacts may not produce the desired visual acuity. RGPs are also suitable for those who need contact lenses after refractive surgery.
When considering GP lenses, be sure to first ask your eye doctor to verify if you truly are a suitable candidate. Who knows…hard lenses might be the right answer for you!
