1. A device for supplying power to an active ocular implant in an eye of a user, comprising:
a spectacle lens with a first main surface and a second main surface;
a light source; and
an optical arrangement which is configured to input couple light from the light source into the spectacle lens and output couple the light from the first main surface of the spectacle lens to the user,
wherein the optical arrangement comprises at least one diffractive element which is arranged in the spectacle lens,
wherein each of the at least one diffractive element includes an associated first end and an associated second end, and
wherein the associated first end and the associated second end each have a different distance from the first main surface and/or each have a different distance from the second main surface, and
wherein the at least one diffractive element comprises a first diffractive element which is configured to receive a collimated light beam and provide the collimated light beam as a divergent light beam.
