I'am reading any kind of information about the so called free-form technology and the possibility to build optical complex surfaces in order to obtain several improvements about the the thicknesses and optical defects of opthalmic lenses.
But , my real question is :
Does it needs the final user this kinds of improvements ?
I read the very interesting articles of Darryl Meister concerning this argument, and it seems that big companies such as Essilor, Zeiss , Hoya look to this new way of the optical techonolgy as the future to warrant to final user to real customize his lenses .
But , my real second question is :
how is possible to be sure to build a real customized optical complex surface ( such as a PAL with internal geometry) when this Complex surface is edged and fixed on a non complex frames and this frames are wear from the users in a noo complex head surface?
The sound of this Free form technology is :
I want to build a Ferrari car using tires of
