Bifocals Round Segment
RS28 Pro/Xact
RS28 has an invisible overlay to the addition power, making it a nice looking alternative to bifocal lenses. It has also the advantage of being available in all materials and with polarised and photochromatic options. This lens is ordered with distance PD and segment height.
For Xact prism compensation is included: compensates for the unwanted prism effect caused by the Z-tilt of the frame.
