While you may be more accustomed to soft contact lenses, a second, less familiar kind of contact lens materials exists: rigid gas permeable (RGP) lenses, also known as oxygen permeable lenses.
In reality, hard lenses involve newer technology than soft contacts, which last longer, can be more effective in improving vision, and provide improved durability and deposit resistance. Additionally they may also be less expensive in the long term than soft lenses. Of course, its advised to first discuss with your optometrist to decide if GPs suit your needs. Our optometry office can help you determine whether you'd be a fit for hard lenses.
Because a GP is constructed from inflexible material, it does a great job of retaining its shape when you blink, which can allow for sharper vision than the average soft lens. Additionally GPs are particularly strong. Though they can crack if stepped on, they don’t tear easily like soft lenses. Also, because they consist of substances that don't contain water, proteins or lipids from your tears don’t stick to GPs as readily as they will to soft lenses. Those of you who are extra particular about quality of vision will most likely opt for RGPs.
Rigid lenses are also a good choice for contact wearers with special considerations such as astigmatism, presbyopia or keratoconus, in which soft lenses may not produce the desired visual acuity. GPs are also preferable for those who need contact lenses after refractive surgery.
When thinking about GP lenses, be sure to first ask your optometrist to ascertain if you definitely are a candidate. You never know…hard lenses could be the perfect answer for you!
