While you may be most accustomed to soft contact lenses, another lesser-known kind of contact lenses exists: rigid gas permeable (RGP) lenses, sometimes referred to oxygen permeable lenses.
Actually, hard lenses involve more modern technology than soft contacts, and they are longer-lasting, can be more effective in improving eyesight, and provide better durability and resistance to protein deposits. Additionally RGP lenses may also be less expensive in the long run than soft lenses. Certainly, you need to first discuss with an eye doctor to decide whether RGPs suit your lifestyle. Our optometry practice can help you figure out if RGP lenses are suitable for you.
Because a GP is composed of inflexible material, it does a good job of retaining its shape when you blink, which can afford sharper vision than the typical soft lens. Additionally GPs are particularly durable. Although they will crack if stepped on, they don’t easily rip like soft lenses. Further, since they're composed of substances that don't include water, proteins and lipids from your tears won't stick to RGPs as readily as they will to soft lenses. Those of you who are especially particular about quality of vision will probably choose GPs.
GPs are also sometimes preferred for those with certain conditions such as astigmatism, presbyopia or keratoconus, where standard contacts may not produce the desired visual acuity. RGPs are also suitable for contact users after refractive surgery.
If you're looking into RGP lenses, make sure to first speak to your optometrist to verify if you truly are a suitable candidate. You never know…hard lenses could be the perfect solution for you!
