The curvature of a sunglass frame can dramatically effect net prescription power often resulting in less clarity, altered depth perception and peripheral distortion. WRAP PREP simulates the effect before the lens is surfaced so that power modifications, astigmatic alterations, as well as prism inductions can be introduced to offset a large portion of these symptoms. A record of prescription modifications is included on the invoice. WRAP PREP is necessary on all but the most minor prescriptions in moderately wrapped frames. $25.00
In more dramatically curved (8 base wrapped) frames, a full digitally compensated lens may be necessary or it may even be necessary to choose a more prescription friendly frame design if the prescription does not meet the process parameters.
