While soft contacts are most common, another lesser-known brand of contact lenses exists: gas permeable (GP) lenses, also referred to oxygen permeable lenses.
Actually, hard lenses involve more modern technology than soft lenses, which last longer, offer greater vision quality, and provide improved durability and deposit resistance. Further RGP lenses may also be cheaper in the long run than soft lenses. Certainly, its best to first consult with your eye doctor to determine whether RGPs suit your needs. Our optometry office can assist you in ascertaining whether you’re a candidate for hard lenses.
Since a GP is made of inflexible material, it maintains its shape well when you blink, which can allow for crisper vision than the typical soft lens. Furthermore GPs are particularly durable. Though they can break if stepped on, they don’t easily rip like soft lenses. Further, since they consist of substances that don’t include water, proteins or lipids from your tears don’t adhere to RGPs as readily as they will to soft lenses. People that are especially fussy about vision quality will probably choose GPs.
GPs are also a good choice for people that have certain conditions such as astigmatism, presbyopia or keratoconus, in which soft lenses may not produce the desired visual acuity. GPs are also a better choice for those who need contact lenses after refractive surgery.
If you’re thinking about GP lenses, be sure to first ask your eye doctor to determine if you truly are a candidate. Who knows…hard lenses could be the perfect answer for you!
