ZEISS pioneered Freeform technology for Rx lenses.
It is now also ZEISS who brings this innovation to FSV by discovering a way to get 
complex freeform single vision lens shapes onto stock FSV lenses.
The advanced Freeform lens design in ZEISS ClearView FSV lenses is based on a complex 
point-by-point optimisation process using 700 free parameters in every lens design.
The result is a Finished Single Vision lens design that is both very thin and flat, and 
achieves excellent optics – with clear viewing from the lens center to the periphery
