The invention discloses an asymmetric lens, a preparation method thereof, an optical device and equipment. The preparation method of the asymmetric lens comprises the following steps: arranging an interdigital electrode on the surface of a substrate; coating the surface of the substrate with an insulating film, and covering the interdigital electrode, wherein the interdigital electrode is connected with a power supply; arranging ultraviolet glue on the side, away from the substrate, of the insulating film; adjusting the structure of the ultraviolet glue through an electromagnetic field formed by the interdigital electrodes, and curing the adjusted ultraviolet glue by utilizing ultraviolet rays. The shape and the curvature radius of the ultraviolet glue can be changed by adjusting the voltage accessed to the interdigital electrode, so that the asymmetric lens can be prepared, and the preparation process of the asymmetric lens is simplified; meanwhile, the ultraviolet glue is used for replacing traditional glass to serve as a raw material, the production cost can be greatly reduced, and large-scale production can be achieved.
