Title
(EN) METHOD FOR PRODUCING CONFORMAL VISOR WITH INTEGRATED OPHTHALMIC LENSES AND CORRESPONDING VISOR
(FR) PROCÉDÉ DE PRODUCTION DE VISIÈRE CONFORME À LENTILLES OPHTALMIQUES INTÉGRÉES ET VISIÈRE CORRESPONDANTE
Abstract
(EN)
The present invention refers to methods for producing a conformal visor (lb) with at least one integrated ophthalmic lens (2, 2a, 2b), wherein the at least one ophthalmic lens (2, 2a, 2b) is built up on the planar visor (la) from layers of printing ink in an additive manufacturing scheme, wherein the layers are obtained through a targeted placement of droplets of printing ink at least partially side by side. The present invention further relates to a corresponding conformal visor (lb) with at least one integrated ophthalmic lens (2, 2a, 2b).
(FR)
La présente invention concerne des procédés de production d'une visière conforme (lb) ayant au moins une lentille ophtalmique intégrée (2, 2a, 2b), ladite au moins une lentille ophtalmique (2, 2a, 2b) étant construite sur la visière plane (la) à partir de couches d'encre d'impression dans un schéma de fabrication additive, les couches étant obtenues par un placement ciblé de gouttelettes d'encre d'impression au moins partiellement côte à côte. La présente invention concerne en outre une visière conforme correspondante (lb) ayant au moins une lentille ophtalmique intégrée (2, 2a, 2b).
