Gas Permeable Contact Lens

Jul 22, 2008
Modern RGP contact lenses have a lot of advantages over soft contact lenses. They are healthier for your eyes, they don't dry out and they last for years. But people are afraid that RGP lenses aren't comfortable. Lets look at the advantages and disadvantages of RGP lenses and how they can work for your eyes.

Whenever they hear the words "Rigid Gas Permeable", most people think "hard contact lenses", confusing RGP lenses with PMMS - hard lenses of the previous generation. RGP are made from a different type of plastic, which makes them more flexible than hard lenses. And their most important feature is high oxygen permeability.

As the name suggests, these lenses are gas permeable - they don't block oxygen flow to your corneas. Oxygen is very important for the health of your eyes because its lack can cause serious eye problems, including inflammation of the cornea.

RGP contacts don't contain any water, so they don't dry out. RGP is ideal for people who work in the dry conditions or outside, in the wind. RGP can also benefit computer users, since people blink less often, when working at the computer, and their eyes can become dry. If you wear soft lenses and your eyes feel dry by the end of the day, consider RGP - they don't suck moisture from your eyes and feel comfortable even at the end of the day.

Another advantage of RGP contact lenses is that they are resistant to protein buildup. Anyone who has worn contacts knows how the protein deposits can make the lenses uncomfortable so this is a boon. This also makes them more durable than regular soft lenses. Although you can?t really see the protein buildup when you look at the lens, it does make a difference to your clarity when you look through the lens so the RGP lenses may even help you see better!

For those people who obtain unsatisfactory results in wearing tints of the regular soft kind, they usually shift to an ocular aid which is porous to oxygen. This is especially true to individuals who are suffering from astigmatism where they do not achieve their desired sight sharpness. As for those who have presbyopia, they choose between designs of bifocal and multifocal which have been proven to work effectively.
