Abstract
A coated lens has a stamping which contains one or more ring-shaped focusing structures. A method for manufacturing such a coated lens is provided in which a coating composition is stamped. The coating composition includes at least one of an epoxide component and a (meth)acrylate component. The ring-shaped focusing structure(s) provide an additional power compared to the central clear zone of the coated lens.
Claims18
A coated lens comprising:
- a coating, the coating being based on a coating composition,
- wherein the coating composition contains:
- a stamping, the coating composition including at least one component selected from the group consisting of at least one epoxide component and at least one (meth)acrylate component, and
- the stamping of the coating containing one ring-shaped focusing structure or more ring-shaped focusing structures,
- wherein the one ring-shaped structure or more ring-shaped structures surround a structure-free central clear zone and form a path that runs from a starting point within the respective structure around the central clear zone and to the starting point again, and
- wherein the one ring-shaped structure or more ring-shaped structures have a constant width.
