Diopter-adjustable lens and design method thereof

The invention relates to a diopter-adjustable lens and a design method thereof, and belongs to the technical field of intelligent eyeglasses lenses. Two lenses are adopted and slightly and relatively translated in the horizontal direction, so that a variable diopter is generated in the optical center of the lenses, only two lenses with the adjustable range of 0-3.00 D need to be designed for a progressive multi-focus lens for adding 300-degree light, the end is adjusted to be 0 when the progressive multi-focus lens is used far, and the end is adjusted to be 3.00 D when the progressive multi-focus lens is used near. The progressive multi-focus lens has the advantages that the problems of far vision and near vision are considered on one pair of glasses, the biggest advantage of the progressive multi-focus lens is that the far vision area and the near vision area are large enough, no channel or blind area is generated, and the optical performance of the far vision area and the near vision area of the novel desig
