ABSTRACT:
A method for laminating an optical assembly and the optical assembly formed thereby. An ultra thin lens is injection molded and may include a bifocal feature. A support lens, e.g. of the single vision type, is provided with a photochromic coating. A flexible two stage compound application process prepares the two lenses for lamination.
