These specially contacts are rigid gas permeable lenses that have an extra-large diameter. They vault completely over your cornea, coming to rest on the whites of your eye (called the sclera). Scleral lenses cover the irregular corneal surface with a rounded optical surface, helping you to achieve clearer vision, even for conditions such as keratoconus.
As the shape of scleral lenses creates a bridge over the eye, it leaves a gap that fills with tears. This pocket of tears enhances comfortable vision for people with dry eyes, which makes scleral lenses a great option for people with severe dry eye syndrome.
