摘要： The present invention discloses a dyeable 1.74 resin lens and a preparation method thereof. The resin lens includes a module layer with a refractive index being 1.74, a dyeable layer with a refractive index being 1.60 is poured on an upper surface of the module layer, an upward curved degree of the dyeable layer is the same as an upward curved degree of the module layer, and a center thickness of the dyeable layer is 0.5-1.2 mm. According to the dyeable 1.74 resin lens of the present invention, a layer of dyeable 1.60plus resin lens is attached to a surface of a 1.74 lens, dyeing performance is good, a visible light transmittance can reach 10-30%, and the blank that the 1.74 lens cannot be dyed is filled.

摘要： 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.
