Device and method for manufacturing an electro-active spectacle lens involving a mechanically flexible integration insert
First Claim
1. An electro-active spectacle lens, comprising:
- an optical element for providing a first optical power;
an insert, disposed within said optical element; and
an electro-active element in optical communication with said optical element and positioned in contact with said insert for providing a second optical power when activated and substantially no optical power when deactivated.

Abstract
An improved device and method for manufacturing electro-active spectacle lenses comprising electronic, electro-active optical, and bulk refractive optical elements is presented. In this method, electronic and electro-active optical elements are mounted to an optically transparent and mechanically flexible integration insert which is separate from any bulk refractive optical element(s). This method is advantageous for the manufacture of such spectacle lenses in that it allows for the mass production of many of the individual elements and enables the integration of the insert with the bulk refractive optical element(s) by multiple means. One such approach involves attaching the insert with a transparent adhesive to a rigid optical substrate and then encapsulating it by means of surface casting. Alternatively, the insert may be placed between the surfaces of a mold filled with an optical resin and encapsulated within the bulk refractive element as the resin is cured.

19. A method for manufacturing an electro-active spectacle lens, the method comprising:
-
positioning an electro-active element within an insert for forming an assembled insert;
laminating a lens blank to a first face of said assembled insert with an optically transparent adhesive for producing a first optical surface of the electro-active spectacle lens;
positioning a mold over a second face of said assembled insert opposite said first face for forming a cavity between said mold and said lens blank;
filling said cavity with an optical resin; and
curing said optical resin for producing a second optical surface of the electro-active spectacle lens. - View Dependent Claims (20, 21, 25)
