Description

Polarized glasses lens Technical Field The application relates to the field of optical lenses, in particular to a polarized eyeglass lens. Background In the technical field of glasses, polarized glasses are important. With the increase of outdoor activities of people, the demand for the protection function of the glasses is also increasing. The polarized glasses not only can block the too strong sunlight from directly irradiating eyes, but also can ensure that a user can clearly see the external environment, which is important for ensuring vision health and improving vision experience. The glasses are widely applied to outdoor exercises such as skiing and other scenes, are favored by a plurality of consumers in daily trips, and promote the product diversification development of the glasses industry. In order to meet the requirements of preventing strong light from directly irradiating eyes and ensuring clear vision, currently, a polaroid is adopted in the mainstream methods of sunglasses, outdoor skiing glasses and the like. Among them, linear polarizers are mostly selected due to price factors. The linear polaroid can effectively regulate the light intensity, so that the light intensity is reduced to a certain degree after natural light is transmitted through the linear polaroid, and a wearer can see objects relatively comfortably under strong light. In addition, circular polarizers are also used in the industry, and are usually implemented by a scheme of adding 1/4 glass slide to a linear polarizer, so as to optimize the damage of linear polarized light to human eyes. However, these existing polarizer solutions have significant drawbacks. The linear polaroid used in large quantity at present can regulate the light intensity, but after natural light passes through the linear polaroid, the polarization vibration state of the light is changed into a single straight line, and the light in various polarization states of the natural light is changed into a single vibration light. The human eyes can damage physiological functions by contacting the light rays with single vibration for a long time. While the circular polaroid can reduce the damage to human eyes, the 1/4 glass slide manufacturing process is expensive, and the large-scale mass production of the glass products is difficult to realize. In addition, in the solar spectrum, besides ultraviolet light, the low-band blue light spectrum can cause great damage to human eyes, and especially has more obvious influence on children, and the existing polaroid scheme is insufficient in protection. Disclosure of utility model The application aims to provide a polarized eyeglass lens, which solves the problem of insufficient synergy of the existing polarized eyeglass lens in aspects of strong light protection, structural strength, polarization state conversion and multiband light filtration. The technical aim of the application is achieved by the following technical scheme that a first coating layer, a first reinforcing layer, a polarizing layer, a color layer, a light conversion layer, a second hardening layer and a second coating layer are sequentially laminated along the light incidence direction, and the polarizing axis direction of the polarizing layer and the molecular orientation direction of the light conversion layer form a certain included angle. By adopting the technical scheme, the structures of the layers cooperate with each other, the first coating layer reduces strong light incidence through color reflection, the second coating layer improves light transmittance through reflection and reflection resistance, the first reinforcing layer enhances the mechanical strength of the lens to ensure stable structure, the polarizing layer realizes basic polarizing function and lays foundation for subsequent polarization state conversion, the color layer filters blue light and light with specific colors in a targeted manner to reduce eye damage, the light conversion layer converts linear polarizing light into a polarization state vibrating in multiple directions to avoid the harm of single polarizing light, the second hardening layer improves the wear resistance of the lens to prolong the service life, the polarizing axis and the molecular orientation of the light conversion layer are arranged at an included angle to ensure that the linear polarizing light is incident to the light conversion layer at an adaptive angle to provide optical basis for efficient polarization state conversion, and comprehensive optimization of protection, strength and optical performance is realized through organic combination of a multilayer structure. Optionally, the first coating layer is a color reflective coating, and at least one of silicon oxide or titanium oxide is used as a film material. Through adopting above-mentioned technical scheme, silica, titanium oxide as stable optical film material, can reduce the highlight direct incidence through colour reflection of light characteri
