AI Technical Summary

Technical Problem

The existing microstructure of the lens surface cannot effectively cope with light from different directions in outdoor environments, resulting in insufficient light adaptability, poor human-computer adaptability, and difficulty in simultaneously achieving anti-glare and visual clarity.

Method used

Employing a gradient microstructure design, the microstructure distribution features a high-density lower section, a transitional middle section, and a low-density upper section. The microstructure density gradually decreases along the vertical direction of the lens. Combined with a prism-shaped microstructure and a CR-39 resin substrate, it conforms to the visual behavior characteristics of human eyes during outdoor activities.

Benefits of technology

It effectively suppresses ground reflections, enhances anti-glare performance, optimizes visual clarity, and meets the visual comfort needs of human eyes during outdoor activities.

Abstract

The utility model discloses a gradient microstructure optical lens adapted to a simulated outdoor environment, which comprises a substrate and a microstructure layer, the microstructure layer comprises a lower high-density area, a middle transition area and an upper low-density area, the microstructure layer is provided with a plurality of uniformly distributed microstructures, and the microstructures are arranged on the substrate. The density of the microstructures is gradually reduced from the lower part to the upper part along the vertical direction of the lens, and the gradient change range of the density of the microstructures is that 2-5 microstructures are reduced per millimeter. According to the gradient microstructure optical lens adaptive to the simulated outdoor environment, targeted anti-dazzle is achieved, and the dense microstructures on the lower portion effectively restrain ground reflection light which accounts for more than 60% of an outdoor dazzle source; visual field definition optimization: the upper sparse arrangement reduces interference to a long-distance visual field; and ergonomic adaptation: the visual behavior characteristic that the downward watching proportion of human eyes is 70% during outdoor activities is met.
