The Advantages of Rigid Contacts


Although soft contacts are most often used, another lesser-known type of contact lenses exists: rigid gas permeable (RGP) lenses, also called oxygen permeable lenses.

Actually, RGP lenses are a more modern technology than soft contacts, which last longer, allow finer vision quality, and offer better durability and resistance to protein deposits. Additionally GP lenses can also be less expensive in the long run than soft lenses. Certainly, you need to first discuss with your eye care practitioner to determine if hard lenses fit your needs. Our optometry office can assist you in ascertaining if you'd be a fit for RGP lenses.

Because a GP is constructed from stiff material, it maintains its shape well when you blink, which tends to provide crisper vision than the average soft lens. Furthermore RGPs are especially long-lasting. Though they will crack if stepped on, they don’t easily rip like soft lenses. Further, since they consist of substances that don't contain water, proteins and lipids from your tears won't adhere to GPs as readily as they do to soft lenses. Those of you who are extra fussy about quality of vision will most likely opt for RGPs.

On the downside, RGPs must be worn consistently to achieve optimum comfort. Further, some people experience “spectacle blur” with hard lenses, which is when eyesight is unclear when the lenses are removed even while wearing glasses. Although the effect is not permanent, it can necessitate full-time GP wear.

If you're looking into RGP lenses, be sure to first ask your eye care practitioner to verify if you definitely are a suitable candidate. Who knows…hard lenses might be the right answer for you!
