1. A device with a spectacle lens for supplying power to an active ocular implant in an eye of a user, the device comprising:
a light source; and
a beam expander arranged in or on the spectacle lens;
wherein the beam expander comprises a first expansion element and a second expansion element,
wherein the device is configured to input couple light from the light source into the spectacle lens and guide the light to the first expansion element,
wherein the first expansion element is configured to receive the light, expand the light along a first direction and guide at least some of the light as expanded light in a second direction to the second expansion element,
wherein the second direction differs from the first direction,
wherein the second expansion element is configured to receive the expanded light, expand said expanded light along the second direction and provide the expanded light as twice expanded light in a third direction via an emission surface,
wherein the third direction at least partly does not extend in the spectacle lens, and
wherein the second expansion element is configured to effectively focus the twice expanded light.
