Abstract
The existing myopia glasses can not correct the retinal peripheral defocusing, which is the main reason for promoting the increase of the number of myopia degrees. The utility model provides a pair of glasses for correcting retinal peripheral defocusing, which consists of a glasses frame, glasses legs and lenses, wherein the lenses are double-optical-region lenses, lens peripheral optical regions are positioned on the peripheral parts of the lenses and are convex lenses, and lens center optical regions are positioned in the center parts of the lenses and are plano lenses, concave lenses, convex lenses, taper hole pleoptic lenses or notch lenses. The glasses can simultaneously correct the retinal center defocusing and the retinal peripheral defocusing, and can effectively prevent the myopia occurrence and the increase of the myopia degrees.
Description
Technical field
