Everything You Wanted to Know About Gas Permeable Lenses

 

Although you may be more accustomed to soft contact lenses, another lesser-known type of contact lenses exists: gas permeable (GP) contact lenses, also referred to oxygen permeable lenses.

Actually, RGP lenses are a more modern technology than soft contacts, which are longer-lasting, allow better vision quality, and offer enhanced deposit resistance. Additionally they can also be cheaper in the long term than soft lenses. Of course, its best to first consult with an eye doctor to determine whether GPs suit your needs. Our optometry office can help you determine whether RGP lenses are right for you.

Because a GP is constructed from stiff material, it retains its form well when you blink, which can afford crisper vision than the average soft lens. In addition RGPs are particularly long-lasting. Although they will break if stepped on, they don’t easily rip like soft lenses. Also, because they consist of materials that don't include water, proteins or lipids from your tears don’t stick to GPs as readily as they do to soft lenses. Those of you who are extra particular about quality of vision will most likely choose GPs.

The biggest disadvantage of GPs is that they must be worn regularly to reach maximum comfort. Further, some people report “spectacle blur” with GPs, which is when vision is blurry when contact lenses are removed even while wearing glasses. Although the effect is not permanent, it can demand constant GP wear.

When checking out hard lenses, be sure to first speak to your eye doctor to ascertain if you truly are a candidate. You never know…hard lenses might be the right match for you!
