Understanding Rigid Gas Permeable Contact Lenses
Although most people wear soft contact lenses, there are various benefits to wearing rigid gas permeable lenses. Unlike soft lenses, rigid gas permeable lenses are firm and hard but not so firm that they prevent oxygen from getting to the eyes like other hard lenses. Patients with astigmatism often prefer the sharpness of rigid gas permeable lenses to traditional soft contact lenses. Rigid gas permeable lenses can also help patients who suffer from dry eyes because they allow tears to get underneath them and form a cushioning layer between the lens and the eye.
Our team at Bogey Hills Vision Center in Saint Charles can help you understand if rigid gas permeable lenses are right for you.
The Advantages of Rigid Gas Permeable Lenses
Today's rigid gas permeable lenses contain silicone, making them more flexible than hard lenses and allowing oxygen and other gases to pass through. As a result, RGP lenses can be larger than hard lenses and can rest comfortably closer to the eye's surface. As a result, they're more comfortable and less prone to falling out. Rigid gas permeable lenses provide better vision than soft lenses, depending on the patient's circumstances.
Since RGB lenses contain less water than soft contact lenses, proteins and lipids in tears do not adhere to them as they do to soft contacts. This makes them deposit resistant, and because they are durable, RGP contact lenses last longer than soft lenses. As long as they are properly cared for, your RGB lenses rarely have to be replaced.
Sometimes, Rigid Gas Permeable Are the Only Choice
Despite these advantages, soft contact lenses continue to be the main contact choice for most people. However, for some patients, we only recommend rigid gas permeable contact lenses. We often recommend these lenses for people with:
- Astigmatism, since they provide superior acuity
- Keratoconus, since they minimize the distortion produced by the cone-shaped cornea that characterizes the condition
- Presbyopia, since they are available as bifocal and multifocal lenses
We also recommend rigid gas permeable lenses for patients who have undergone refractive surgery.
