While you may be more accustomed to soft contact lenses, a second, less familiar kind of contact lens materials exists: gas permeable (GP) lenses, sometimes called oxygen permeable lenses.
In reality, hard lenses involve more modern technology than soft contacts, and they are longer-lasting, can be more successful in improving eyesight, and offer enhanced deposit resistance. Additionally GP lenses may also be cheaper in the long term than soft lenses. Certainly, you need to first consult with an eye care practitioner to determine if RGPs fit your needs. Our optometry office can assist you in ascertaining whether hard lenses are suitable for you.
Since a GP is made of stiff material, it retains its form well when you blink, which can provide crisper vision than the typical soft lens. Furthermore RGPs are especially durable. Although they will break if stepped on, they don’t tear easily like soft lenses. Also, because they're made of materials that don't include water, proteins and lipids from your tears don’t stick to GPs as easily as they do to soft lenses. Those of you who are extra fussy about vision quality will probably opt for RGPs.
Rigid lenses are also an often preferred option for people that have certain conditions such as astigmatism, presbyopia or keratoconus, where standard contacts may not produce the desired visual acuity. RGPs are also preferable for those who need contact lenses after refractive surgery.
If you are considering RGP lenses, be sure to first ask your optometrist to ascertain if you definitely are a suitable candidate. Who knows…hard lenses might be the perfect match for you!
