ABSTRACT:
A corrective/ophthalmic lens comprising an impact lip extending from an anterior lens edge and a radial groove adjacent and parallel to the lens lip posterior surface, an eyewear system containing a corrective/ophthalmic lens and a method of making a lens is provided. The lens impact lip size is variable, determined by frame function and the degree of impact protection that is necessary. A posterior surface of the lens impact lip is beveled with a curvature that preferably substantially matches and coincides with the lens anterior curves, producing a lip with no corrective, low residual power effect or negative image effects. Due to the absence of image change and effects through the lens impact lip, in one aspect the present invention eliminates restrictions to the size of the impact lip.
