In addition, the surface of the lens body is provided with the blue light prevention layer, and blue light in light can be blocked by the blue light prevention layer, so that the lens has a certain blue light prevention effect; the blue light prevention layer is transparent, so that the light emitting effect of the whole lens cannot be influenced; the inclined surface is arranged on the bottom surface of the mounting seat, so that the mounting seat can be conveniently mounted on the car lamp by utilizing the inclined surface, and further mounting is facilitated; and the inclined plane can form certain isolation space between the position that is used for installing lens on mount pad side and the car light for reduce the wearing and tearing to the mount pad to a certain extent, prolonged life. Therefore, the anti-dazzle device not only can improve the anti-dazzle effect, but also has the advantages of high light softness, convenience in installation, high installation stability, good anti-blue light effect and long service life.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.
Examples are given. A lens for a car lamp with an anti-dazzle effect is formed as shown in figures 1 to 7 and comprises a round mounting base 1, wherein a positioning notch 2 is arranged on the side wall of the mounting base 1; one side of the positioning notch 2 is provided with a clamping groove 3 positioned on the top surface of the mounting seat 1, and the middle part of the clamping groove 3 is provided with a clamping block 4; a hemispherical convex surface 5 is arranged in the middle of the top surface of the mounting seat 1, and a plurality of uniformly distributed convex points 6 are arranged on the inner side surface of the convex surface 5; the end part of the outer side surface of the convex surface 5 close to the mounting seat 1 is provided with a frosting layer 7 which is distributed annularly; and a hemispherical lens body 8 is filled between the convex surface 5 and the mounting seat 1.
A transparent blue light-proof layer 9 is laid on the surface of the lens body 8; the edge of the bottom surface of the mounting seat 1 is provided with an inclined surface 10, and the distance from the end part of the inclined surface 10 close to the convex surface 5 to the center of the mounting seat 1 is greater than the distance from the end part of the inclined surface 10 far away from the convex surface 5 to the center of the mounting seat 1; the mounting seat 1, the convex surface 5, the salient points 6 and the lens body 8 are all made of transparent glass.
The working principle is as follows: during specific work, when light irradiates the lens body 8 from the mounting seat 1, the light can enter the mounting seat 1 downwards to be refracted by a first layer; the light rays are refracted by the mounting seat 1 and can directly enter the lens body 8 to carry out the second layer of refraction work, because the whole lens body 8 is hemispherical (namely the whole lens can form a plano-convex lens so as to convert a point light source into parallel light), the light rays refracted in the lens body 8 can irradiate the inner side surface of the convex surface 5 from the top surface of the lens body 8 at different emergent angles; the inner side surface of the convex surface 5 is provided with the plurality of uniformly distributed convex points 6, so that light rays can be contacted with the convex surfaces 6 before being irradiated on the convex surface 5, the emergent angles of the light rays can be further dispersed by utilizing the convex points 6, the emergent angles of the light rays finally can not be concentrated, the phenomenon of glare caused by over concentration of the emergent angles of the light rays is avoided, and the anti-glare effect is improved; because the outer surface of the lens body 8 is also provided with the blue light prevention layer, the blue light prevention layer can be used for absorbing blue light wave bands in pipelines, so that the damage of the blue light wave bands in light to human eyes is reduced, and a certain blue light prevention effect is achieved; and the frosting layer 7 of convex surface 5 surface tip can carry out diffuse reflection work to the light that jets out from the edge to when improving marginal light's soft degree, can play the effect that increases the area of illumination edge fuzzification, increased area of illumination to a certain extent.
