  • Publication number: 20190196224
    Abstract: A dual defocus lens is disclosed in the present invention. The dual defocus lens comprises a refractive-error correction part, a positioning part and a periphery part. The refractive-error correction part comprises a central optical region, a first defocus region and a second defocus region. The first defocus region, the second defocus region, the positioning part and the periphery part are all concentric to the central optical region having the same center as the refractive-error correction part. The first defocus region and the central optical region have different diopters individually for correcting the positions of imaging on the retina. The second defocus region having small radius of curvature provides shorter focus for imaging in the front of the retina. Thus, the retina will not be elongated or deformed gradually due to the image beyond the retina so that the myopia can be greatly controlled.
