(57) 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.
