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.
