Abstract

Described is a production line (1) for the production of ophthalmic lenses (10) that comprises a molding apparatus (2), at least one molding-shell-storage (3), at least one molding-shell-transporting-means (4), at least one operating unit (5), and preferably also a demolding apparatus (7) and molding-shell washing means (8). Said molding apparatus (8) and said demolding apparatus (7) are both suitable for fully automatized molding and demolding of ophthalmic lenses (10) and lens treatments such as coloring, hard coating and anti-reflective coating of lenses (10).
