Shamir Duo™ Bifocal Polycarbonate Transitions®

Shamir Duo™ Bifocal Polycarbonate Transitions®

The Shamir Duo™ Bifocal Polycarbonate Transitions® lenses are advanced Freeform® lenses that offer surface continuity, eliminating the visible line. It also offers optical continuity, eliminating image jump and loss of image. By eliminating these problems associated with traditional bifocal lenses, Shamir Duo™ maintains a natural, distortion-free visual path as the eye moves from one vision zone to another.

Transitions® Signature lenses rapidly darken when outdoors and fade back to clear when indoors. Choose from one of the Transitions® Signature tints of Grey, Brown or Graphite Green, or step outside the box and choose from one of the new Transitions Style Colors (limited to specific material and lens design availability) of Amber, Amethyst, Emerald or Sapphire.

Polycarbonate lenses have become the standard for safety glasses, sports goggles and children’s eyewear. They are less likely to break than regular plastic CR39 lenses, They are also are a good choice for rimless eyewear designs where the lenses are attached to the frame components with drill mountings.
