Abstract
Ophthalmic lenses and method of manufacturing ophthalmic lenses that include automated steps are disclosed.
Claims28
A method for forming a pattern of optical features on a surface of an ophthalmic lens having a lens axis, comprising:
- receiving the ophthalmic lens on a stage;
- positioning the ophthalmic lens relative to a first apparatus by causing relative motion between the first apparatus and the stage;
- measuring light transmitted or reflected by the ophthalmic lens or a surface property of the ophthalmic lens using the first apparatus;
- determining a position of the lens axis based on the measured light or surface property;
- obtaining information about an alignment of the pattern of optical features relative to the lens axis;
- aligning the ophthalmic lens with a laser system based on the position of the lens axis;
- and
- exposing locations of the ophthalmic lens to a laser beam from the laser system to form the pattern of optical features on the ophthalmic lens according to the information about the alignment.
