Although you may be most accustomed to soft contact lenses, a second, lesser-known kind of contact lens materials exists: gas permeable (GP) lenses, sometimes referred to oxygen permeable lenses.
Actually, hard lenses are a newer technology than soft lenses, and they are longer-lasting, allow greater vision quality, and provide increased durability and deposit resistance. Further GP lenses may also be cheaper in the long term than soft lenses. Certainly, its best to first discuss with an eye care practitioner to determine whether RGPs suit your needs. Our optometry staff can assist you in ascertaining whether RGP lenses are right for you.
Because an RGP is composed of inflexible material, it maintains its form well when you blink, which tends to allow for crisper vision than the typical soft lens. Additionally GPs are extremely long-lasting. Although they will break if stepped on, they don’t tear easily like soft lenses. Further, because they're composed of materials that don't include water, proteins or lipids from your tears don’t adhere to RGPs as readily as they do to soft lenses. People that are extra particular about vision quality will most likely opt for GPs.
RGPs are also an often preferred option for those with certain conditions 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 looking into hard lenses, be sure to first ask your optometrist to ascertain if you definitely are a candidate. Who knows…hard lenses could be the perfect solution for you!
