Abstract:
The present invention relates to a contact lens for presbyopia and, more specifically, to a contact lens for presbyopia, providing both a far-distance vision area and a near-distance vision area in one contact lens, and continuously forming a lens magnification of the far-distance vision area and the near-distance vision area of the dominant eye and the non-dominant eye while changing the sizes of the far-distance vision area and the near-distance vision area of two eyes according to the dominant eye and the non-dominant eye, such that an intermediate-distance area is partially overlapped, thereby continuously providing a near-distance vision area at a far distance by a neural summation phenomenon that selects a clearly visible image in both eyes.
