The invention discloses an ultraviolet protective lens and a preparation method thereof. The ultraviolet protective lens includes a glass substrate, and is characterized in that a high refractive film and a low refractive film are alternately plated on the glass substrate, the thickness of the high reflective film is 10-30nm, the thickness of the low refractive film is 25-50nm, and the high refractive film and the low refractive film are alternated by 10-25 times. The ultraviolet protective lens prepared by the method provided by the invention has high visible light transmission and good ultraviolet protection effect, realizes perfect unification of ultraviolet protection and normal observation, and solves the problem that when sun glasses are worn to block ultraviolet and control cataract, the visible light transmittance is low and can affect human eye observation.
