Abstract
The invention relates to a method for producing a polarising ophthalmic lens adapted to the eye/head behaviour of the wearer thereof and to said lens. The inventive ophthalmic lens comprises several areas associated to differently oriented polarising filters. The size and position of at least certain areas are determined according to the lens wearer's eye/head behaviour.
Claims12
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.
