AI Technical Summary

Technical Problem

Existing myopia control lenses have insufficient contrast control, resulting in unsatisfactory optical fidelity. The microlenses in the lenses are usually evenly distributed, while human eye cells are not evenly arranged, so the myopia control performance of conventional lenses is not ideal.

Method used

Design a lens with adjustable optical path difference structure, including a lens element and a microlens array. The first side of the lens element is convex. The microlens array extends in groups within the ultrastructural region. The lens group diverges along the target axis, which is curved in space. The size and distribution characteristics of the microlenses can be adjusted to accommodate patients with different degrees of myopia.

Benefits of technology

By rationally scattering light, the signal differences between adjacent cones and the overstimulation of retinal photoreceptor cells are reduced, thereby improving the accuracy and adaptability of myopia correction and meeting the myopia correction needs of specific populations.

Abstract

The utility model provides an optical path difference regulation and control structure lens, and relates to the field of optical lenses, the optical path difference regulation and control structure lens comprises a lens member, the lens member comprises a micro lens array, the micro lens array comprises a plurality of micro lenses arranged in a sequential order to form an ultramicrostructure area, the first side of the lens piece is convex, the end part of the lens piece is correspondingly provided with a planar target extension surface, the plurality of micro lenses form a plurality of lens groups, and each lens group is radially divergent and extends to the end part from the first side of the lens piece. On the basis of the retina contrast theory, signal difference between adjacent cones and over-stimulation of retina photoreceptor cells are reduced by reasonably scattering light, and high-contrast signals are reduced; each lens group can be independently configured to correspond to specific human eye cell distribution characteristics, the lens can be adapted to patients with different myopia degrees by adjusting the distribution characteristics of the lens groups, and the problems of insufficient contrast control and inaccurate myopia correction of the current myopia prevention and control lens are solved.
