Ophthalmic lens and frame glasses with same

By setting multiple first and second refractive zones on the ophthalmic lens and combining them with a dense light-adding design, the problems of visual quality and wearing compliance of existing lenses in suppressing myopia progression are solved, achieving effective myopia control and reducing individual differences.

Abstract

The invention provides an ophthalmic lens and frame glasses with the same. The ophthalmic lens comprises a plurality of first refractive regions and a plurality of second refractive regions, the plurality of first refractive regions being closer to the center of the ophthalmic lens than the plurality of second refractive regions, an incident light beam passing through the plurality of first refractive regions being projected in a region between 10 degrees and 20 degrees aside the fovea of the retina macular of the wearer, the distance between the second dioptric areas is larger than that between the first dioptric areas, and the areas, except the first dioptric areas and the second dioptric areas, on the ophthalmic lens have correction refractive power based on correction of ametropia of the eyes. The plurality of first refractive regions and the plurality of second refractive regions have refractive power different from the correction refractive power. The high-density myopia defocus area is arranged near the central optical area to carry out intensive light addition to form myopia defocus, so that more stimulation can be given to the retina, and the elongation of the ocular axis is inhibited.
