Digital Surfacing
It is not simple to explain the many issues with wrap around digitally surfaced lens designs.
Having a lens design from any lens company for digial surfacing is like having the avionics for an FA 18 airplane, (used by the Navy Blue Angels). Having the avionics does not mean you can fly with the Blue Angels. Having the lens design software does not mean you can make a lens. Freeform lenses are not as simple as plug and play.
A big issue with wrap around sunwear and PALs is the location of the optical center compared to the geometric center.
