Why GP’s Might be Right for You

 

While soft contact lenses are most often used, a second, lesser-known brand of contact lens materials exists: gas permeable (GP) lenses, also referred to oxygen permeable lenses.

In truth, GP lenses are a newer technology than soft lenses, which are longer-lasting, can be more effective in improving vision, and offer enhanced deposit resistance. Additionally RGP lenses may also be cheaper in the long term than soft lenses. Certainly, its advised to first consult with an eye care practitioner to decide whether hard lenses fit your needs. Our optometry office can help you determine if you'd be a fit for GP lenses.

Since a GP is composed of stiff material, it does a great job of retaining its shape when you blink, which tends to allow for clearer vision than the average soft lens. Furthermore RGPs are extremely durable. Though they can break if stepped on, they don’t easily rip like soft lenses. Further, because they're made of materials that don't include water, proteins or lipids from your tears don’t adhere to GPs as readily as they do to soft lenses. People that are extra fussy about vision quality will probably choose RGPs.

The biggest disadvantage of GPs is that they need to be worn regularly to reach maximum comfort. Further, there are some who report “spectacle blur” with hard lenses, which is when vision is unclear when contact lenses are taken out even while wearing glasses. Though the effect is only temporary, it can demand full-time GP wear.

When looking into hard lenses, be sure to first speak to your eye doctor to ascertain if you definitely are a candidate. You never know…hard lenses could be the right match for you!
