The present invention is embodied in ophthalmic lenses having a first lens surface that is described by a continuous, gradual increase in optical power that proceeds without inflection points of discontinuities across substantially the entire useable optical area of this lens surface, and an opposite surface of the lens configured to cooperate with the power gradation of the first surface to provide a desired prescription, including at least one stabilized area of optical power. The power gradation of the first surface increases from one edge of the useable area to substantially the opposite edge, and may increase according to linear or non-linear relationships. In another preferred embodiment, the two lens surfaces cooperate to create two stabilized areas of optical power, for a prescription with near-viewing and distance-viewing values.

The invention discloses a floor drain device automatically cleaning hair. The floor drain device automatically cleaning hair comprises a floor-drain installing base, a floor-drain body is arranged onthe floor-drain installing base, a containing mechanism capable of winding and containing impurities such as hair is arranged on one side of the floor-drain installing base, and a scraping sweeping mechanism capable of scraping the impurities such as the hair to the containing mechanism is arranged on the floor-drain installing base. According to the floor drain device, the scraping sweeping mechanism is used for cleaning away the impurities such as the hair clogged on a floor-drain cover hole in time, it is guaranteed that floor-drain water normally flows into a sewer line, the clogging phenomenon of the sewer line disappears accordingly, and meanwhile the impurities such as the hair in the containing mechanism can be periodically cleaned away conveniently.

The invention provides a container as well as a lighting control method thereof, and a computer readable storage medium. The container comprises a cabinet body, a door body, a camera device, a first lighting module, a second lighting module and a controller, wherein the door body is arranged at an opening of the cabinet body in a retractable way; the camera device is arranged on the cabinet body;the first lighting module is arranged on the cabinet body and is used for providing light for the interior of the cabinet body; the second lighting module is arranged on the cabinet body and is used for providing light for the camera device; the controller is connected with the first lighting module and the second lighting module; the controller is used for controlling the working states of the first lighting module and the second lighting module according to the opening and closing states of the door body. According to the container provided by the invention, the working states of the first lighting module and the second lighting module are controlled by means of the controller according to the opening and closing states of the door body, so that the service lives of the first lighting module and the second lighting module are effectively prolonged under the premise that the information such as the commodities and the price tags is displayed in a highlighted way so as to stimulate consumption.
