Abstract:
A self-adhering contact lens made of flexible material, the lens for adhering to cornea and scleral regions of an eye, the cornea and sclera each having a radius of curvature, the radius of curvature of the sclera being greater than the radius of curvature of the cornea, the lens comprising:a central lens portion optically shaped for viewing interior regions of the eye, the central lens portion having an interior concave surface with a radius of curvature R.sub.1 approximating the radius of curvature of the cornea for contacting the cornea; andan outer flange formed integrally with the central lens portion extending radially outwardly from the central lens portion, the outer flange having an interior concave surface extending from the interior concave surface of the central lens portion, the interior concave surface of the outer flange for contacting the sclera and having a radius of curvature R.sub.2 that is greater than the radius R.sub.1 but less than the radius of curvature of the sclera, the outer flange being shaped for deflecting relative to the central lens portion for conforming the interior concave surface of the outer flange to the sclera.
