Vision Dynamics’ permaTINT™ Line Expanded to Include CR-39

Louisville, Kentucky, June, 2023 — Vision Dynamics is pleased to launch an expanded line of pretinted semi-finished single vision lens blanks to include CR-39, available in 2, 4, 6, and 8 base.

Our pre-tinted line of 1.67, Trivex®, polycarbonate and now CR-39 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 edgeto-edge color performance.

“Tinting 1.67, Trivex®, polycarbonate and CR-39 lens blanks has always been a time-consuming process for optical labs,” shares John Dippold, President. “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 CR-39 permaTINT product is available in grey C. 1.67, Trivex®, and poly are available in grey C, brown C and green-grey 15. The poly permaTINT product is additionally available in orange, blue, rose, and yellow. Custom color matching services are available for unique products. With fixed 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.
