Although you may be more familiar with soft contact lenses, a second, lesser-known brand of contact lenses exists: rigid gas permeable (RGP) contact lenses, also referred to oxygen permeable lenses.
In truth, GP lenses involve newer technology than soft contacts, and they are longer-lasting, offer finer vision quality, and offer better durability. Further GP lenses can also be cheaper in the long run than soft lenses. Certainly, you need to first consult with an eye doctor to decide whether hard lenses fit your lifestyle. Our optometry practice can help you figure out if GP lenses are right for you.
Because a GP is made of stiff material, it retains its shape well when you blink, which tends to allow for clearer vision than the typical soft lens. Furthermore GPs are particularly long-lasting. Although they will break if stepped on, they don’t easily rip like soft lenses. Also, since they consist of materials that don't include water, proteins or lipids from your tears don’t adhere to GPs as easily as they do to soft lenses. Those of you who are especially fussy about vision quality will probably choose RGPs.
On the downside, RGPs need to be worn regularly in order to reach optimum comfort. Additionally, there are some who experience “spectacle blur” with GPs, which is when eyesight is blurry when contact lenses are removed even while wearing glasses. Though the effect is only temporary, it can necessitate full-time GP wear.
If you're checking out hard lenses, be sure to first ask your eye care practitioner to determine if you truly are a suitable candidate. Who knows…hard lenses could be the right answer for you!
