While soft contact lenses are most common, another less familiar brand of contact lenses exists: rigid gas permeable (RGP) contact lenses, sometimes referred to oxygen permeable lenses.
Actually, RGP lenses involve newer technology than soft contacts, which are longer-lasting, are often more successful in improving vision, and offer enhanced deposit resistance. Further GP lenses can also be cheaper in the long run than soft lenses. Of course, its advised to first consult with an eye doctor to decide if RGPs suit your needs. Our optometry office can help you figure out whether RGP lenses are suitable for you.
Because a GP is constructed from inflexible material, it does a good job of maintaining its form when you blink, which tends to afford sharper vision than the typical soft lens. Furthermore GPs are especially long-lasting. Though they will break if stepped on, they don’t tear easily like soft lenses. Further, because they consist of materials that don't include water, proteins and lipids from your tears won't adhere to RGPs as easily as they do to soft lenses. Those of you who are especially fussy about vision quality will most likely opt for RGPs.
GPs are also an often preferred option for people with special considerations such as astigmatism, presbyopia or keratoconus, where soft lenses may not produce the desired visual acuity. GPs are also suitable for those who need contact lenses after refractive surgery.
If you're looking into GP lenses, make sure to first speak to your eye care practitioner to ascertain if you definitely are a candidate. Who knows…hard lenses might be the perfect answer for you!
