Abstract
The present invention refers to methods for producing a conformal visor (1b) 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 (1a) 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 (1b) with at least one integrated ophthalmic lens (2, 2a, 2b).
