EYEGLASS LENSES WITH MINIMIZED EDGE VISIBILITY

摘要

Eyeglass lenses have at least a portion of their edge shaped to reflect light away from an eye of a wearer, such as the edge being disposed at an acute angle with respect to a principal axis of the lens, toward the back surface of the lens. Alternatively or additionally, the edge may include a plurality of edge surfaces disposed at an acute angle with respect to a principal axis of the eyeglass lens, toward the back surface of the eyeglass lens, or at least one edge surface may be disposed at an acute angle with respect to the front surface of the lens and at least one other edge surface may be disposed at an acute angle with respect to the back surface of the lens. As yet another alternative, the edge may be rounded with progressive angles to have an edge axis directed away from the wearer's eye.

1. An eyeglass lens comprising:
a curved front surface, adapted to be away from an eye of a wearer ; a curved back surface, adapted to be toward the eye of the wearer; and an edge extending between the front surface and the back surface, at least a portion of the edge selectively shaped to direct edge reflected light away from the eye of the wearer.
