While you may be more accustomed to soft contact lenses, another lesser-known kind of contact lenses exists: gas permeable (GP) contact lenses, also referred to oxygen permeable lenses.
Actually, GP lenses involve newer technology than soft contacts, and they are longer-lasting, can be more effective in improving eyesight, and offer enhanced deposit resistance. Additionally GP lenses may also be less expensive in the long run than soft lenses. Of course, you need to first consult with your eye care practitioner to decide whether GPs fit your needs. Our optometry office can assist you in ascertaining whether you’re a candidate for RGP lenses.
Since an RGP is composed of inflexible material, it does a great job of retaining its shape when you blink, which can provide sharper vision than the typical soft lens. Additionally RGPs are particularly long-lasting. Although they can crack if stepped on, they don’t tear easily like soft lenses. Further, since they're composed of materials that don't contain water, proteins or lipids from your tears won't stick to GPs as easily as they do to soft lenses. People that are especially fussy about quality of vision will probably choose RGPs.
RGPs are also a good choice for contact wearers with special considerations such as astigmatism, presbyopia or keratoconus, where standard contacts may not produce the desired visual acuity. RGPs are also a better choice for contact users after refractive surgery.
When checking out GP lenses, be sure to first speak to your eye care practitioner to ascertain if you truly are a candidate. You never know…hard lenses could be the perfect answer for you!
