Although soft contact lenses are most common, a second, lesser-known brand of contact lenses exists: rigid gas permeable (RGP) contact lenses, also called oxygen permeable lenses.
Actually, RGP lenses are a more modern technology than soft contacts, which are longer-lasting, can be more successful in improving vision, and offer better durability and deposit resistance. Additionally they can also be cheaper in the long term than soft lenses. Certainly, its best to first consult with your eye doctor to decide whether RGPs suit your needs. Our optometry staff can help you figure out whether you’re a candidate for GP lenses.
Since a GP is composed of stiff material, it maintains its shape well when you blink, which can allow for clearer vision than the average soft lens. Additionally RGPs are especially durable. Although they can crack if stepped on, they don’t tear easily like soft lenses. Also, because they consist of materials that don't include water, proteins or lipids from your tears won't adhere to RGPs as easily as they will to soft lenses. People that are especially fussy about vision quality will probably choose GPs.
GPs are also an often preferred option for people with certain conditions such as astigmatism, presbyopia or keratoconus, in which standard contacts may not produce the desired visual acuity. RGPs are also a better choice for those who need contact lenses after refractive surgery.
When thinking about GP lenses, be sure to first ask your eye care practitioner to find out if you truly are a suitable candidate. Who knows…hard lenses could be the perfect match for you!
