Seiko Optical Products Launches 1.67 PolarThin Lenses


MAHWAH, N.J.—Seiko Optical Products of America has introduced PolarThin, one of the thinnest and lightest polarized sunwear available.

Michael J. Rybacki, senior vice president of sales and marketing said, “The 1.67 Semi-Finished PolarThin features Precise Film Positioning, a proprietary process where the film is located 0.4mm from surface center to edge (patent pending). The polarizing film is placed closer to the surface of the blank, resulting in lightweight and fashionable lenses that can be surfaced as thin as 1.3 mm center thickness, compared to all other manufacturers 1.8∼2.0 mm center thickness.”

Seiko’s 1.67 PolarThin offers 11 accurate Base Curves including a 0.50B. The accurate and consistent curvature is ideal for all free-form designs as well as conventional single-vision, according to Seiko. PolarThin blanks are made with high index MR-10 resin, which is less sensitive to heat and does not readily contract or expand—factors that can lead to warping and coating deterioration.

PolarThin 1.67 is available in gray and brown polarized film colors and features a high index double hard coat primer which provides increased impact resistance and reduces fringe interference. “PolarThin has been tested to show it exceeds ANSI Z80.1 at a 1.3mm center thickness by over nine times,” added Rybacki. ■
