PITTSBURGH--Following the release of the TR O Seg round-segment bifocal in Transitions technology last year, Three Rivers Optical laboratory, (www.threeriversoptical.com) based here, is introducing the TR O Blended Seg. The lens is available in plastic, polycarbonate, mid-index, high-index as well as Transitions and polarized in all materials. The Rx range is -10.00 to +6.00D, with an add range from +0.50 to +5.00D.

Three Rivers recommends the TR O Blended Seg for a variety of uses, including drilled rimless frames, childrens’ eyewear, progressive nonadapts, frames with B measurements that are too short for progressives.

“We recognized a gap in the availability of Transitions Lenses, and released the TR O Seg last year, followed by the TR O Blended Seg this year. “We were able to create a customized process to meet our customers’ needs that allows them to give their patients the best technology in the lens material and design right for them,” says Steve Seibert, president of Three Rivers.

Combining an innovative, patented milling process and specialized programming, Three Rivers Optical is able to modify patented design characteristics to grind a blended segment bifocal.  The design is available in three varying-sized segments 22mm, 25mm, 28mm, to match current frame sizes and wearer lifestyles. Larger sizes can be ordered by special request.
