Gas Permeable Contact Lens

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.

Gas permeable contact lenses are actually not novel in the industry as they were launched in late 1970's. However, this ocular aid is much newer than the regular soft. Most of this kind of tints is integrated with a comfortable plastic known as silicone. The mentioned element is porous to oxygen where the aftermath is healthier vision, avoidance to deposits and better durability.

RGP lenses are made from silicone which gives them more flexibility and allows oxygen to permeate through the lens. The RGP type lenses allow more oxygen than most soft contacts and this means more comfort as well as better eye health.

Try stepping on gas permeable contact lens and you will discover that it is not that easy to break. Unbelievable as it may sound but it is brought about by certain materials that do not hold any water. Due to such, this ocular aid does not attract lipids and proteins that originate from the glands that excrete tears. As for the regular soft, when you tear it apart, it will only require a less amount of force.

RGP lenses are quite pricey. But when consider that RGP lenses usually last for 2-3 years, the overall cost isn't so high. You would spend much more replacing soft contact lenses every 2 weeks. A concept of a rigid lens being in your eye scares most people, because they don't believe that such a lens can be comfortable. But in fact it is - people who wear RGP contact lenses report that a minute after they put the lens in they feel like there is nothing in their eyes.
