The invention relates to an anti-
ultraviolet wear-resistant helmet lens provided with gradually changed colors and used for the vehicle. Plastics is adopted as the
raw material, and produced into the lens through injection molding. The helmet lens is characterized in that anti-
ultraviolet (UV) agent with the weight ratio of 0.3-0.5 percent is added into the plastic
raw material, and the plastics is produced into the transparent lens through uniform mixing and injection molding; the lens is washed through water and dried, water-soluble dye
powder is adopted to be dissolved in water according to the water-dye
powder proportion of 100: 0.01-1.0, stirred uniformly and heated to 80 to 100 DEG C, the lens is fixed on a rack or held in the hand, immerged into
dyeing solution and moved vertically, gradient dying and overlapping are then performed for one to two minutes, and the lens is respectively cleaned through
cleaning agent and water, and then the lens with gradually changed colors can be obtained. The anti-
ultraviolet wear-resistant helmet lens has the advantages of anti-ultraviolet function, through which the
radiant heat of harmful ultraviolet and
infrared rays emitted from the sun can be prevented and certain
skin protection function can be achieved; the effect of gradually changed colors, which can protect the eyes from fatigue, and can provide the product with colorful and beautiful appearance.
