The present invention discloses an anti-blue light anti-infrared resin lens having a refractivity of 1.50, and a preparation method thereof. The lens comprises 100 parts by weight of CR39 resin monomer, 0.5-5 parts by weight of an initiator, and 1.0216-30.6 parts by weight of an additive, where the additive includes an anti-infrared absorber, a blue light absorber, and a hardness modifier at a weight ratio of 0.0005-0.5:0.001-10:1-10, the initiator is benzoyl peroxide, dicumyl peroxide, or 1,1-di-tert-butylperoxy-3,3,5-trimethylcyclohexane. The resin lens prepared in the present invention has both blue light absorption effect and near-infrared absorption effect and is capable of being dyed as needed to have the effect of sunglasses, while the quality of the lens is guaranteed. The resin lens is a new type of multifunctional resin lens.
