Abstract
Myopia progressive addition peripheral defocus correction spectacles belong to health care spectacles. Conventional progressive addition lenses cannot correct hypermetropic defocus at the periphery of a retina, thereby failing to prevent the growth of a myopia degree. A lens is divided into a lens peripheral optical area and a lens center optical area, wherein the lens peripheral optical area is at the periphery of the lens and made into a convex lens for correcting the hypermetropic defocus at the periphery of the retina, thereby controlling the growth of the myopia degree; and the lens center optical area is at the center of the lens and made into a progressive addition lens for correcting central defocus of the retina, thereby improving distant vision. The spectacles keep the characteristics of a progressive addition lens that far, medium, and close distance objects can be seen clearly and overcome the technical defect that the progressive addition lens cannot correct the hypermetropic defocus at the periphery of the retina. The spectacles are a wear for 6- to 12-year-old children to prevent and treat myopia.
