While you may be more accustomed to soft contact lenses, another lesser-known brand of contact lens materials exists: gas permeable (GP) lenses, sometimes called oxygen permeable lenses.
In truth, RGP lenses involve more modern technology than soft lenses, and they last longer, offer finer vision quality, and offer enhanced deposit resistance. Additionally they may also be cheaper in the long run than soft lenses. Of course, you need to first discuss with an optometrist to determine if hard lenses fit your needs. Our optometry staff can assist you in determining if RGP lenses are suitable for you.
Because an RGP is composed of inflexible material, it maintains its form well when you blink, which can allow for clearer vision than the average soft lens. Furthermore GPs are particularly strong. Although they will 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 don’t stick to GPs as readily as they will to soft lenses. Those of you who are extra fussy about quality of vision will probably opt for GPs.
GPs are also an often preferred option for people with special considerations such as astigmatism, presbyopia or keratoconus, where standard contacts may not fit properly or offer enough variety. GPs are also preferable for contact users after refractive surgery.
If you're considering GP lenses, be sure to first speak to your eye doctor to determine if you really are a suitable candidate. You never know…hard lenses might be the perfect solution for you!
