Although you may be more familiar with soft contact lenses, a second, less familiar kind of contact lenses exists: gas permeable (GP) lenses, also called oxygen permeable lenses.
In reality, RGP lenses are a newer technology than soft lenses, which are longer-lasting, are often more successful in improving eyesight, and provide better resilience. Additionally they can also be less expensive in the long run than soft lenses. Certainly, its advised to first consult with your eye doctor to decide if hard lenses suit your lifestyle. Our optometry practice can assist you in ascertaining whether you’re a candidate for hard lenses.
Since an RGP is made of stiff material, it does a good job of retaining its shape when you blink, which can afford crisper vision than the typical soft lens. Additionally RGPs are especially long-lasting. 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 and lipids from your tears don’t stick to RGPs as easily as they will to soft lenses. Those of you who are extra fussy about quality of vision will most likely opt for RGPs.
Rigid lenses are also an often preferred option for people with certain conditions such as astigmatism, presbyopia or keratoconus, where soft lenses may not produce the desired visual acuity. GPs are also suitable for those who need contact lenses after refractive surgery.
When thinking about RGP lenses, make sure to first ask your eye doctor to find out if you truly are a candidate. Who knows…hard lenses might be the right answer for you!
