Abstract: An ophthalmic lens and technologies relating to the ophthalmic lens including an intermediate portion that includes a portion in which a power is strengthened and thereafter weakened when the lens is viewed in an X direction from the center toward the periphery, and includes a portion A? in which the power is strengthened and thereafter weakened when the lens is viewed in an X? direction from the center toward the periphery, the X? direction being exactly opposite to the X direction, the power being strengthened in the portion A and the portion A? to be stronger than a far-vision power of a far-vision portion or a near-vision power of a near-vision portion that is arranged in a ring shape along an outer edge of the intermediate portion.

Abstract: To provide an ocular lens capable of securing a stable image in a distance portion and a near portion, and suppressing a generation of blurring or ghosting of the image. A progressive multifocal far and near contact lens is provided, having a distance portion for aiding a far vision, a near portion for aiding a near vision, and an intermediate portion in which power is progressively changed between the distance portion and the near portion, and a power distribution of a lens optical region along a direction of a vertical axis N of the lens optical region is set according to a predetermined function.
