Abstract
A combined structure of a lens and s soft elastomer is disclosed. The lens has an upper edge that includes a combining portion, wherein the combining portion has at least one surface formed as a roughened surface. The elastomer is integrated with the combining portion as a unity through an over-molding process. By roughening the surface of the combining portion, enhanced engaging force and all-around combination between the elastomer and the combining portion can be achieved. The combined structure prevents the elastomer and the lens from separation and thereby enhances industrial safety.

A combined structure of a lens and a soft elastomer, the combined structure comprising:
- the lens having an upper edge, said upper edge including a combining portion, wherein the combining portion has at least one surface formed as a roughened surface, and wherein said roughened surface of said at least one surface of said combining portion is configured with a plurality of openings;
- and
- the soft elastomer filling said plurality of openings and thus permanently joined with the combining portion of the lens into an integral unit through an over-molding process, wherein the soft elastomer firmly and tightly engages with the roughened surface of the combining portion of the lens to achieve all-around combination of the combined structure.
