Abstract
A device that utilizes a method to heat dyes to color plastic lenses. The device is an electrically heated outer tank containing a heat transfer medium. An inner tank containing a dye solution is placed in side the outer tank. Lenses are placed in the dye solution along with sensor probes and microprocessor control to maximize dye diffusion into the lenses and minimize boil over of the tanks. Spill containment and agitation stirring are also features which enhance diffusion of dye into the lenses while minimizing boil over.
