Abstract
Ophthalmic lenses and method of manufacturing ophthalmic lenses are disclosed. The lenses are manufactured with markers for aligning the lenses in a particular rotational alignment with respect to a spectacle frame. The lenses can also be provided with scattering parts for defocus to prevent myopia.
Claims25
A method, comprising:
- providing an ophthalmic lens having opposing surfaces defining a prescription (Rx) optical power of the ophthalmic lens, the opposing surfaces further defining an optical center of the ophthalmic lens, and the ophthalmic lens comprising an edge defining a perimeter of the ophthalmic lens;
- obtaining a pattern of three or more optical elements;
- rotating the pattern about an optical axis of the ophthalmic lens;
- and
- after rotating the pattern, forming the optical elements on the lens according to the pattern,
- wherein the three or more optical elements each have an optical effect different from the Rx optical power of the ophthalmic lens, and after forming the optical elements the Rx optical power of the ophthalmic lens remains unchanged,
- wherein (i) the pattern is radially asymmetric, or (ii) the ophthalmic lens has at least one optical or structural characteristic that is radially asymmetric with respect to the ophthalmic lens;
- and
- wherein (i) the ophthalmic lens is radially asymmetric and the pattern is formed on the ophthalmic lens according to a specified orientation, or (ii) one or more optical or structural features are formed within the ophthalmic lens, on at least one surface of the ophthalmic lens, and/or at edge of the ophthalmic lens, the one or more optical or structural features specifying a rotational orientation of the ophthalmic lens.
