Although soft contacts are more common, a second, lesser-known kind of contact lenses exists: rigid gas permeable (RGP) lenses, also referred to oxygen permeable lenses.
Actually, GP lenses are a more modern technology than soft lenses, which last longer, allow better vision quality, and offer enhanced deposit resistance. Further they may also be less expensive in the long run than soft lenses. Of course, its advised to first consult with an eye doctor to determine if hard lenses suit your needs. Our optometry office can assist you in determining whether GP lenses are right for you.
Since a GP is constructed from stiff material, it does a good job of retaining its shape when you blink, which tends to provide sharper vision than the average soft lens. In addition GPs are extremely long-lasting. Although they can crack if stepped on, they don’t easily rip like soft lenses. Further, since they consist of substances that don't contain water, proteins or lipids from your tears won't stick to GPs as easily as they do to soft lenses. Those of you who are especially particular about quality of vision will probably opt for GPs.
On the downside, GPs need to be worn consistently in order to achieve optimum comfort. Additionally, some people report “spectacle blur” with GPs, which is when vision is unclear when the lenses are removed even while wearing glasses. Although the effect is only temporary, it can demand full-time GP wear.
If you're considering hard lenses, make sure to first ask your eye doctor to find out if you really are a suitable candidate. Who knows…hard lenses could be the right solution for you!
