| 1. A process for producing a polarizing ophthalmic lens divided into several zones associated with polarizing filters having
variable respective orientations, the process comprising the following steps so that the lens is adapted to the eye/head behavior
of a wearer of said lens:
/1/ characterizing relative amplitudes of respective movements of the wearer's eyes and head;
/2/ as a function of a result from step /1/, defining the zones of the lens associated with each polarizing filter orientation;
and
/3/ fabricating the lens by incorporating into said lens, in each zone defined in step /2/, a polarizing filter having the
orientation corresponding to said zone.
