Advantages & Disadvantages of Using Gas Permeable (GP) Contact Lenses
The most common type of contact lenses are the soft contact lenses. However, there is a category of contact lenses which are lesser-known and these are: the gas permeable contact lenses (also known as RGP's) and lenses that are oxygen permeable.
Definition of Gas Permeable Contact Lenses
There are 3 types of contact lenses: the PMMA lenses (or hard contact lenses) which were used way back then, soft lenses that are made from gel-like plastic (most universal kind of contact lens) and lastly the GP contact lenses. GP contact lenses are rigid, yet these should not be puzzled with the "old-style hard contact lenses" which are now outdated.
During late 1970's gas permeable contact lenses were first presented. Most GPs has silicone which makes them more flexible as compared to PMMA. Since silicones are oxygen permeable, this permits oxygen to pass through the cornea and to the gas permeable contact lenses producing improved eye health and superior comfort. As a matter of fact, oxygen is more transmitted by GPs as compared to the conventional contact lenses.
Gas permeable contact lenses also present enhanced vision, deposit resistance and stability than soft contact lenses. It's easier to clean and because they are long-lasting, patients can save more in the long run.
Why GP lenses are very comfortable to wear?
Gas permeable contact lenses are custom made for every individual. Your eye doctor will measure your eyes for the accurate fitting of the shape of your cornea and recommend lenses with the size, corrective power and curvature that suits your eyes.
Technology advancements have also made GP contact lenses thinner in design, larger diameters and with added consistency of smooth edges than ever before. Furthermore, eye doctors are already using modern methods to map a person's eye topography which allows the back surface of the lens to align with the cornea.
