Embodiment Construction

[0009] The structure of the present invention is relatively simple and will not be described repeatedly. Only issues requiring further clarification are presented. The birefringent functional film or sheet 3 referred to in the present invention has various physical names, and it is also called an optically anisotropic functional film or sheet, a retardation film or sheet, a retardation film or sheet, and a wave plate. No matter what name is used, it refers to the same type of optical functional film or sheet. The physical essence of this optical functional film or sheet is that it has birefringence properties. Therefore no matter which name is adopted, it falls within the protection scope of the present invention.

[0010] The birefringent functional film or sheet 3 used in the present invention has been shown through specific experiments that better color-changing performance can be achieved by using a multi-layer birefringent functional film or sheet 3 composite layer.

Abstract

The invention discloses a colored polarizing sun glasses which comprises a glasses frame and a glasses lens and is characterized in that the lens structure is a complex structure of the transparent base material (1), the polarizing film or sheet (2), the twice refraction function film or sheet (3), the polarizing film or sheet (4), the transparent base material (5).

Description

(1) Technical field [0001] The invention relates to the technical field of daily life, especially sunglasses. (2) Background technology [0002] The current sunglasses are divided into three categories: the first category is ordinary sunglasses. The lenses are divided into two types: (1) general black lenses that can weaken light, have single functions and poor decorative effects; (2) sunglasses with dyed lenses. Dip-dyeing technology is adopted to enrich the color of the lens and improve the decorative effect of the sunglasses. The second category is the so-called photochromic sunglasses. By adding certain chemical components into the lens material, the color of the lens can be changed under different light conditions. This change in color shade is not a true color change, because the lens cannot transition from one color to another. The third category is polarized sunglasses. The function of using polarizers to weaken the light, and at the same time, this kind of lens...
