HD:SV

Caledonian Optical's Single Vision HD:SV lens takes advantage of our in­-depth knowledge in personalised ophthalmic lens design to achieve the highest performance in clarity and comfort. Our SV Zone design has been engineered with the capacity to produce any type of Single Vision free­form lens, no matter the frame, material, base curve or prescription.

This design is not just for standard prescriptions fitted to conventional Rx frames; HD:SV is also a high performance design perfect for complex orders such as high prescriptions or lenses optimised for wrap frames.

Thanks to Digital Ray­-Path technology, each pair of HD:SV lenses can be calculated by entering real personalisation parameters or, when this data is not provided, using default values for these parameters.

Maximum performance can only be reached using all the personalisation parameters, however, for frames without pronounced wrap angles, the quality reached using the default values will be close to maximum.
