  • Rigid Gas Permeable Contact Lenses

    Rigid Gas Permeable contact lenses (RGP lenses) are worn by about 15 percent of contact lens wearers. Unlike hard plastic lenses, RGP lenses are gas permeable. That is, they allow oxygen to pass through to the cornea. They are less expensive and more durable than soft contact lenses, and provide wearers with clearer, sharper vision.
    Unlike soft contact lenses, RGP lenses have a low water content and therefore, resist protein deposits and bacteria. Because they are rigid, they hold their shape when the wearer blinks, allowing for crisper vision. Other benefits include ease of handling and ease of care. Because they do not contain water, proteins from the eye do not build up on the lens, so the lens stays cleaner, and requires less maintenance.
    RGP's are not for every patient. Because of their rigid form, they require more break in time for the patient to become comfortable with wearing the lenses. Also, if you discontinue wearing your RGP lenses for a few days, it may be difficult to become used to wearing them again. RGP's differ from soft contacts in that becoming comfortable with wearing a rigid lens requires the patient to wear their lenses all the time. Soft contact lens users may discontinue wearing their lenses for a few days, and immediately be comfortable with having them inserted again.
    Rigid Gas permeable contact lenses are also known as Oxygen Permeable contact lenses. The plastic of these lenses is breathable, and they must be custom fit to the shape of the cornea. Only your eye care professional can help you decide which contact lenses are right for you.
