Gas Permeable Contact Lenses Provide Better Vision And Eye Health
Many people are shifting their vision away from soft contacts to experience the benefits of rigid gas permeable contact lenses. Although they are stiffer than the soft contacts, they are not your grandfather's hard contacts, which are not in use today. Made of silicone and fluorine, gas permeable contact lenses allow oxygen to freely penetrate and reach the eyes while resisting the build up of bacteria, helping to maintain the health of the eyes.
Not only do they help the eyes stay healthier, they are easier to put in and take out due to their harder surface. Because gas permeable contact lenses are stiffer than soft contacts they retain their shape better and provide sharper, crisper vision unlike the softer ones that can lose their appeal and reduce their effectiveness. The curvature, correction ability and size of the contacts are determined by a complete examination, but unlike soft contacts, gas permeable contact lenses will retain their shape longer, reducing the frequency of buying replacements.
Some Contacts Attract Bacteria
With soft contact lenses, which are about 79 percent water, seem to attract bacteria and other foreign materials, holding them close to the eyes. The benefit of the initial improved comfort may quickly be lost as wearers find they are prone to build up protein deposits and require cleaning more frequently than rigid gas permeable contact lenses. Additionally, with the penchant for deposit build up, soft contacts may become more uncomfortable over time.
Due to the ability of oxygen to pass through gas permeable contact lenses they are the most often type used for extended wear. The eye is able to breathe and their resistance to build up of protein and bacteria help maintain the overall health of the eyes. Additionally, persons with astigmatisms are better served with rigid gas permeable contact lenses,
Helps Smooth Uneven Corneas
Another advantage to rigid gas permeable contact lenses is that person suffering from corneal distortion, an irregularity or warping of the cornea, can be helped with rigid lenses and may not be able to wear soft contacts that tend to adjust to the shape of the cornea. By wearing the rigid gas permeable contact lenses the cornea can be smoothed out, providing sharper vision.
Only a qualified and licensed optometrist can prescribe any type of contacts and many eye professionals are pushing for the use of rigid gas permeable contact lenses to promote better eye health and to reduce the chances of developing eye infections due to bacteria on the contacts,
