<p>The method involves obtaining an ametropia correction of a wearer for a vision distance, and other ametropia corrections of the wearer for other vision distances. Principal and secondary vision zones (10, 20) of an eyeglass are determined. The secondary zone is divided into two sets of regions (21, 22). Parameters of the eyeglass in the principal vision zone are determined. Other parameters of the eyeglass in the regions of one set are determined based on one of the latter ametropia corrections and assigned to the set of regions. The eyeglass is produced according to the parameters. An independent claim is also included for a multifocal ophthalmic lens forming a finished or semi-finished eyeglass, comprising principal and secondary vision zones.</p> |
