Gas Permeable Contact Lenses Review

Gas Permeable Contact LensesGas permeable contact lenses may not be as well known as the soft type, but for many conditions these lenses can be ideal when soft lenses will not work or are not preferred. They may also be called rigid gas permeable contact lenses or even at times oxygen permeable lenses. A common misunderstanding is that many people think these lenses are the hard ones first available a long time ago, and that is not the case. Original lenses did not allow oxygen through the barrier, but this new type first developed in the 1970s does.

There are some benefits that gas permeable contact lenses offer over the soft variety. Better results can usually be seen for many conditions, and this is true with toric contact lenses as well. GP lenses are very durable and meant to last longer, so while they may cost more initially they are actually cheaper over time. The rigid lenses have a higher resistance to deposits on the lens, so there is nothing to cause discomfort while wearing them. Cleaning is very simple, and in some people soft lenses are not an option because of specific vision problems.

Gas permeable contact lenses also have the benefit of being smaller than soft lenses where diameter is concerned. A drawback is that these lenses are not comfortable when first worn, and require some adaptation before they can be worn all the time. With a contact lens prescription for the gas permeable type it may be necessary to continue to wear glasses in the beginning for much of the time.

Because gas permeable contact lenses are not as soft or flexible they can cause discomfort until your eye adjusts. Another factor is that these lenses are cleaned and worn every day. Some people are extremely sensitive to many of the contact lens cleaner solutions, and this can be a problem. With soft contacts disposable products may eliminate this issue, but with GP lenses the cost of special requirements when creating them is not cheap and disposable options would not be cost effective.
