Method of making eyewear having flexible frame with rigid lens retainer

摘要

A lens is permanently engaged with a substantially rigid lens retaining apparatus to form a lens unit during a formation molding process of the lens retaining apparatus. The rigid lens retaining apparatus is permanently engaged with a substantially flexible eyewear frame during a formation molding process of the frame. Therefore, a secure attachment of lenses to the substantially flexible eyewear frame through rigid lens retaining apparatus is provided.

主权项

1. A method of making eyewear comprising:
(a) providing at least one lens; (b) providing a lens retainer molding device for molding at least one lens retainer for engaging the at least one lens: (c) forming the at least one lens retainer with a first molding material in first molding process using the lens retainer molding device with the at least one lens present during a first molding process, producing at least one lens unit having both the at least one lens retainer and the at least one lens, the at least one lens retainer being substantially rigid and permanently engaging at least a part of a peripheral portion of the at least one lens; (d) providing a frame molding device for molding a frame for holding the at least one lens unit; and (e) forming the frame with a second molding material in a second molding process using the frame molding device with the at least one lens unit present during a second molding process, the frame being substantially flexible and permanently engaging the at least one lens retainer of the at least one lens unit to form at least a front section of the eyewear.
