METHOD AND APPARATUS FOR FORMING SUNGLASS LENSES WITH A PREDETERMINED GRADIENT

摘要

A method for forming sunglass lenses with a predetermined optical gradient, namely a polarized gradient, or transmissivity gradient in which a gradient pattern is provided on an oriented sheet. The oriented sheet is incorporated into a lens to provide the lens with the associated gradient.

1. A method for providing a sunglass lenses lens with a predetermined optical polarization gradient, comprising:
printing an oriented sheet with dye in a pattern in which the density of the printed dye varies in a predetermined pattern under the control of a printer from one position on the oriented sheet to a different position on the oriented sheet, the printed dye providing a gradient in polarization across the surface thereof; and, drying the printed oriented sheet with the printed dye thereon; whereby utilizing the dried printed oriented sheet may be utilized as a layer within a sunglass lens.
