Single Vision Wrap™
Six individual aspheric designs deliver
precise optics and an expansive viewing zone in oversized
fashion and performance wrap frames for Rxs from -6.00D to

range. Only KBco Single Vision Wrap Solutions lenses come
in a blank size large enough in diameter to take on
oversized wrap frames.

Using an ordinary
spherical 8 base lens for prescriptions that should go on
other base curves results in:
●
Optical Distortion
●
Unwanted Astigmatism
●
A highly restricted viewing
zone (The "Keyhole Effect")
Optics and the
viewing zone can be compromised further by the
significant amount of Panoramic (Face Form) Angle
found in 8 base wrap frames.
● This occurs
because the angle of the wearer's line of sight through a
lens in a wrap frame is different than through their lenses
in regular frames.
