AI Technical Summary

Technical Problem

In the prior art, myopia glasses are effective methods to prevent and control myopia deficiency in adolescents.

Method used

A circular microstructure array myopia lens is designed. The positive center of the front surface of the lens is a single focus visual area and the surrounding is a microstructure defocus area. The microstructure defocus area includes a plurality of annular band defocus lens arrays, arranged from the inside to the outside. The forward defocus amount of the first annular band defocus lens array and the second annular band defocus lens array is greater than the forward defocus amount of the third to nine annular band defocus lens arrays.

Benefits of technology

Through the compact and dense defocus lens structure, visual transition is achieved, myopia is defocused, corrected intervention, avoid irritation of the eyeball, and prevent the growth of the eye axis.

Abstract

The utility model discloses a circular microstructure array myopic lens, which comprises a lens, a single-focus visual area is arranged right in the center of the front surface of the lens, a micro-structure defocusing area is arranged on the periphery of the single-focus visual area, and the micro-structure defocusing area is formed by arranging a plurality of annular defocusing lens arrays from inside to outside. The first belt defocusing lens array and the second belt defocusing lens array are close to a single-focus visual area, the defocusing lenses are compact and dense in structure and play a role in visual transition, and the third belt defocusing lens array, the fourth belt defocusing lens array, the fifth belt defocusing lens array, the sixth belt defocusing lens array and the ninth belt defocusing lens array can project images around an object to the position in front of the retina to form myopia defocusing. Through correction intervention, eye axis growth caused by eyeball stimulation is avoided, and the degree is deepened.
