When most people think of contact lenses, they think of soft contact lenses. However, today there are a variety of different types available to suit an individual's unique eye condition. One such contact lens is the gas permeable (GP) contact lens which is also referred to as oxygen permeable and rigid gas permeable lenses.
What are Rigid Gas Permeable Contact Lenses?
Gas permeable lenses (GP) were introduced in the late 1970s and have now replaced the PMMA type contact lens. They are more rigid than soft lenses. They are different than the original hard contact lenses that were made of PMMA which did not permit oxygen to reach the eye. Oxygen being able to reach the eye is vital to good eye health. GP integrate some silicone in the material making the them flexible and the silicone is oxygen-permeable. They are comfortable to wear and healthy for the eye because the oxygen is able to reach the eye.
Benefits of Gas Permeable Lenses
GP can correct certain corneal abnormalities that soft contact lens are unable to correct. They provide clear vision and minimize the need to refocus. As well, they retain their shape when the wearer blinks and do not easily tear. These contacts are more durable than soft contacts and they are easy to clean because the materials in the lenses do not contain water so protein and debris does not stick to the lens.
When cared for properly, these lenses can last for a few years or until it is time for a prescription update. New wearers should be aware that it can take time to get used to these lenses so it is important to be patient. In addition, it is important to practice proper daily cleaning and maintaining practices.
Another Option - Hybrid Contact Lenses
Hybrid lenses are another option for contact lens wearers. These lenses combine a rigid, gas-permeable center with a soft outer ring. This type of lens is a popular choice as they provide comfort for the wearer while providing the clear vision of GP contacts. You can get this type of contact lens if you have such conditions as presbyopia and keratoconus.

You can normally get contacts lenses at greatly discounted prices, often up to 70%. When you shop on a contact lens retailer's site, make sure it is an established and reputable company.
