VDL Expands PermaTINT Poly SFSV Line

Louisville, Kentucky, October, 2013 — Vision Dynamics is pleased to launch our expanded line of pre-tinted polycarbonate semi-finished single vision lens blanks in 2, 4, 6 and 8 base.

Our pre-tinted polycarbonate SFSV lens blanks for sport, computer, and driving prescriptions integrate easily in conventional and digital surfacing lines. Our proprietary colorization process applies a uniform density layer on the front surface of the blank and includes a hard coat. Surfacing does not affect the color layer so the finished lens has consistent edge-to-edge color performance.

“Tinting polycarbonate lens blanks has always been a difficult process for optical labs,” shares John Dippold, VP Operations. “With permaTINT, we eliminate the production issues associated with tinting in a traditional dye tank. This includes blotching, inconsistencies from hard coat variations and light or dark centers. Labs experience a reduction in overall breakage and improve service time by not losing the lens in the final step of the production process,” added Dippold.

The permaTINT product is available in seven standard color options including, grey C, brown C and green-grey 15. Custom color matching services are available for unique products. With uniform color density across the complete Rx range, permaTINT lenses are ideal for processing free-form progressives.


“Adding pre-tinted permTINT saves time, simplifies workflow and improves service,” said Eric Lindquist, National Account Manager. “It is a great product solution for solving a universal problem,” concluded Lindquist.
