A bifocal corneal contact lens and method of making same wherein a carrying lens or lens body has a corrective optical prescription for viewing distant objects and has a near viewing portion or bifocal segment fused in an indentation of one surface thereof, said near viewing portion having a corrective optical prescription for viewing near objects, the lens body having a predetermined power to correct for distant vision and the segment having a power equal to the exact refractive add of the eye to correct for near vision and having a size in relation to the size of the pupil of the eye so that the optimum focal points of the lens body and segment are spaced apart a distance less than the radius of the eye and actually overlap and blend together to give a clear and continuous image when the gaze is shifted between near and distant objects without any optical jump or fuzziness of vision occurring.
