Abstract: The present invention is to provide a method for easily evaluating whether or not a relative positional shift generated between both surfaces of a bi-aspherical type lens is within an allowance during the manufacturing process of the bi-aspherical type lens. According to the evaluation method of the progressive-addition lens of the present invention, first, powers of the progressive-addition lens at a plurality of are measured to obtain an actually measured power distribution. Next, a comparison power distribution created based on the actually measured power distribution and a defective power distribution prepared in advance are compared with each other to perform similarity search between the both. Thereafter, whether or not the comparison power distribution and the similar to each other is determined based on the result of the similarity search step, and if it is determined that the comparison power distribution and the defective power distribution are similar to each other, then the progressive-addition lens is evaluated as defective.

Abstract: A pair of spectacle lenses for binocular vision. In each of the pair of spectacle lenses for binocular vision, when an inner horizontal direction of each of the spectacle lenses is a direction toward the nose of a user who wears the spectacle lenses, and an outer horizontal direction of each of the spectacle lenses is a direction toward an ear of the user, a portion for viewing an object at finite distance is provided and a shape of a base out prism is formed in the position such that a line of sight of a user viewing an object through the portion is directed to a direction that is different from a direction from the object.

Abstract: In a progressive-addition lens having a progressive surface on one side and an aspherical or atoroidal surface on the other side, the lens shape is designed so that a high degree of aberration correction can be carried out on the periphery of the lens and the distance power and addition power of the lens acting on the eye of a wearer substantially correspond to the distance power and addition power measured by a lens meter. A progressive-addition lens includes a progressive surface and an aspherically designed surface formed of an aspherical or atoroidal surface, and the reference point of the aspherically designed surface is located in the vertical direction of the lens below a prism reference point of the progressive surface and above a near design reference point.
