While you may be most familiar with soft contact lenses, another less familiar brand of contact lenses exists: gas permeable (GP) lenses, also called oxygen permeable lenses.
In truth, GP lenses are a newer technology than soft lenses, and they last longer, offer better vision quality, and offer enhanced deposit resistance. Further RGP lenses may also be cheaper in the long term than soft lenses. Certainly, you need to first consult with an eye care practitioner to determine if hard lenses suit your lifestyle. Our optometry practice can help you determine whether hard lenses are right for you.
Since a GP is made of stiff material, it does a great job of maintaining its shape when you blink, which tends to afford sharper vision than the average soft lens. Furthermore RGPs are especially long-lasting. Though they will crack if stepped on, they don’t easily rip like soft lenses. Further, because they're made of substances 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 probably choose GPs.
GPs are also a good choice for people that have certain conditions such as astigmatism, presbyopia or keratoconus, where soft lenses may not produce the desired visual acuity. GPs are also suitable for contact users after refractive surgery.
When considering RGP lenses, make sure to first speak to your eye doctor to ascertain if you really are a suitable candidate. You never know…hard lenses could be the perfect match for you!
