Combined sunglasses lens structure convenient to install

Abstract

The invention provides a combined sunglasses lens structure convenient to install. The combined sunglasses lens structure comprises an elastic connecting sleeve used for being installed in a glasses frame and a lens body embedded in the connecting sleeve. The connecting sleeve is further provided with a detachable photochromic lens located on the front side of the lens body. A first mounting groove for mounting the lens body and a second mounting groove for mounting the photochromic lens are formed in the connecting sleeve; a plurality of positioning holes which are arrayed along the circumferential direction of the connecting sleeve are formed in two side walls of the first mounting groove; an anti-skid column is arranged in each positioning hole, and the bottom of each anti-skid column is fixed to the bottom of the corresponding positioning hole through an adhesive; the groove width of the second mounting groove is smaller than the thickness of the photochromic lens; the photochromic lens comprises a resin substrate, and an antireflection film, a photochromic film and a wear-resistant layer which are sequentially arranged on the resin substrate; the current situation that the photochromic lenses of the existing sunglasses lenses are rapidly switched in a color-changing or non-color-changing scene is improved.

Description

technical field [0001] The invention relates to the field of sunglass lenses, in particular to a combined sunglass lens structure that is easy to install. Background technique [0002] Sunglasses can adjust the luminous flux to adapt to the pupil, so that people can play a protective role when the light intensity exceeds the adjustment ability of the human eye. In principle, it reflects light of various wavelengths in the light through the lens to avoid blue light and ultraviolet light. Light that is harmful to the eyes, such as light, can pass through, and can ensure the normal vision of people's eyes. [0003] White light in nature is mainly composed of blue light, green light, and yellow light. Among them, green light and yellow light have less energy and are less irritating to the eyes, while blue light has a high energy band and can directly reach the retina of the fundus. Therefore, Blue light is easy to cause eye fatigue; in addition, the infrared light that exists i...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the present invention provides an easy-to-install combined sunglass lens structure, which solves the problem of directly attaching a color-changing film to the outside of the existing sunglass lens to adapt to discoloration. Issue with replacing spectacle lenses in scenes that do not require photochromic lenses
