Many years have gone by since Luxottica Group took over Sferoflex (in 1982), yet the Sferoflex glasses are manufactured still today in the very same plant located in Rovereto, Italy, where they were originally born.

A special spring mechanism inside the hinge makes the temples flexible and allows the glasses to adapt to the size of every face without causing any annoying constraints, and thus providing an extremely comfortable fit.
