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.
