AI Technical Summary

Technical Problem

Conventional single-focus optical lenses fail to adequately address the progression of refractive errors such as myopia and hyperopia, particularly causing poor focusing on nearby objects and worsening myopia over time, and existing diffusion technologies compromise visual performance and lens durability.

Method used

A lens element with hidden diffusion regions, oriented to minimize diffusion in the forward principal direction and enhance diffusion in peripheral vision, is designed to slow myopia progression while maintaining central vision clarity.

Benefits of technology

The lens element effectively suppresses myopia progression by optimizing diffusion patterns to reduce scattering in the foveal region and enhance peripheral diffusion, thereby maintaining visual performance and lens durability.

Abstract

The present invention relates to a lens element (11) intended to be worn in front of the wearer's eye under wearing conditions, comprising a substrate (12) having a front surface (12F) and a rear surface (12R), wherein the substrate (12) includes a group of hidden diffusion regions (14) having a lateral diffusion pattern and a light diffusion pattern exhibiting minimal diffusion with respect to the lateral diffusion pattern in the forward principal direction, and the hidden diffusion regions (14) are positioned such that the forward principal direction passes through the point of rotation (ERC) of the eye model under wearing conditions.
