Gas Permeable Contact Lenses

Oxygen and gas permeable contact lenses are rigid, smaller, more comfortable to wear and more healthy for the eyes than ever before. But, these contacts are not to be confused with the old style hard contact lens. Hard contact lenses were made of a material called polymethyl methacrylate (PMMA). A PMMA lens was difficult to get used to because it was so uncomfortable to wear. The material from which it was made was not permeable and therefore did not let the eyes breathe. Soft contacts came into play in 1971. Soft contacts are actually the most popular type of lens. They are a lot more comfortable than the PMMA lens. Soft contacts also allow for plenty of oxygen to get through to the eyes. The one big distinction between the soft and the gas permeable contact lenses is that the gas permeable (GP) lens is smaller.

The advantages of GPs far outweigh the detriments. Because of the rigidity of the GP lens, it may take some time to get used to wearing this type of lens. GPs are not as rigid as the old style contact and are much smaller. GPs have more durability than the soft type. Gas permeable contact lenses are breakable, yet not easily torn; unlike soft contacts. Even so, breaking them takes some effort. No water is used to plump up this lens which makes it resistant to the effects of tears and perspiration. Lipids and proteins adhere to soft lenses when tears are present or perspiration gets into the eyes. The lens becomes cloudy and makes the vision somewhat blurry. GP contacts are resistant to the deposits that tend to cling to soft lenses. And they won't aggregate debris at same pace as the soft lens will. GPs are much easier to clean and keep clean. Gas permeable contact lenses are also long lasting; which means less expense in the long run. Where a soft lens may last a day or a month, the GP lens lasts for years. Of course, a change is necessary if a person's prescription changes. In the log run, GPs can provide better overall vision.

GPs are often prescribed for people who can't obtain acceptable vision using a soft lens. These individuals may include: 1) People who need or want to have optimal vision, 2) Some people who have astigmatism who want or need better visual acuity, 3) Those with presbyopia, 4) People with keratoconus, and 5) Those who have had refractive surgery. Optimal vision can be achieved when using gas permeable contact lenses. Some lens wearers are sensitive to certain materials and have a high level of allergic reactions. Because of the fact that GPs do not contain polyaminopropylbiguanide, chlorhexidine, polyquad, or BAK, patients can rest easy that they are good candidates for these lenses. Purified benzyl alcohol and no preservatives add to this surety. "Now the Lord is that Spirit: and where the Spirit of the Lord is, there is liberty. 18. But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord. (2 Corinthians 3:17-18)

There is a downside to wearing gas permeable contact lenses. This type of lens must be worn consistently. When wearing soft lenses, a person can chose to wear them or not; for any period of time. When a person does not wear GPs for a while and resumes wearing them, there is a period of discomfort. Also, after having worn the GPs for a while, and taking them out, a person's vision may appear blurry for a period of time. Realistically, if a person chooses GPs they are making more of a commitment to keeping them in, than if they choose a soft lens. Plus, dealing with GPs, a person must put in the maintenance time required to preserve the integrity of the lens. There is a manufacturer who has come up with a combination lens of sorts. The company is capitalizing on the fact that one of the primary barriers to using the GPs are that they are uncomfortable. The company has taken the soft lens and plopped gas permeable contact lenses right into the center. The resulting contact is both comfortable and provides more visual acuity. It has been approved by the FDA since 2005. This lens type is available for many eye conditions including: presbyopia, keratoconus and post-surgery.

For many people, even though they need them, their vanity will not allow them to be seen in public in a pair of eyeglasses. The manufacturers of contacts know this. Industry leaders also know that a whole new generation of people who will have some level of presbyopia are on their way up the pike. They have been and continue to work on alternatives to regular prescription eyeglasses. It is not common knowledge that contact lenses can also be bifocal, trifocal, or even progressive. Eyeglass lenses are often regarded this way, but contacts are not. There are lots of people who think there is no hope for them every being able to wear contacts because of their type of visual condition. But that's not exactly true. Multifocal contacts are being developed for just about every type of eye condition. The variety of lenses which are being developed each year for people with various eye conditions is phenomenal. Though many may be initially created in a soft lens, one can be sure that gas permeable contact lenses are also in the mix.
