Personalized large-front-curvature polarized sunglasses and preparation method thereof

Abstract

The invention relates to the technical field of manufacturing and processing of glasses, and particularly relates to a pair of personalized large-front-curvature polarized sunglasses and a preparation method thereof. Compared with the prior art, various data like the refractive index of an optical frame chosen by the wearer are combined according to the design parameters like the angle of inclination and the degree of curvature of a mirror surface of a large-front-curvature mirror bracket and the personalized parameters like the diopter, the pupil distance and the eye position of the individual wearer and according to the normal angle range of a human eye vision, a corrective compensation value calculation processing method and a partition thinning processing method are adopted, the problem of manufacturing of the polarized sunglasses with diopter and the problem of difficulty in dispensing the glasses are fundamentally solved, and the requirement of correcting the diopter of a large number of shortsightedness patients and the requirement of hoping to wear the polarized sunglasses are both met.

Description

technical field [0001] The invention relates to the technical field of glasses manufacturing and processing, in particular to a personalized large face curved polarized sun glasses lens and a manufacturing method thereof. Background technique [0002] Due to the special function of effectively filtering the clutter interference of reflected light on the surface of objects, polarized sunglasses lenses make the vision clearer and the colors more saturated, so they are known as the most high-end sunglasses lenses. Matched with fashionable and trendy sunglass frames or sports frames, it can bring more perfect glasses protection, more comfortable visual experience and more prominent personality to the wearer. However, due to the basic shape of this type of frame design, which is large and curved, the original polarized lenses with diopters cannot be assembled because of the thick edges when preparing such glasses. , and due to the change of the optical axis angle caused by the l...

Problems solved by technology

However, due to the basic shape of this type of frame design, which is large and curved, the original polarized lenses with diopters cannot be assembled because of the thick edges when preparing such glasses. , and due to the change of the optical axis angle caused by the large face bending and being close to the wearer's face, the inevitable diopter deviation and prism refraction and other complicated reasons, so the traditional production and matching process of polarized lenses with diopters cannot be configured at all. Large-face curved polarized sunglasses with diopters that meet the requirements limit the needs of a large number of myopia patients who have diopter correction requirements and want to wear this type of polarized sunglasses
