摘要： A 1.74 refractive index polarized resin lens and a preparation method thereof are provided. The lens includes upper and lower resin material layers with a refractive index of 1.74, a PVA polarizing film layer is arranged between the two resin material layers, and the surface of the PVA polarizing film is coated with a single monomer polyurethane binder. According to the present invention, the PVA polarizing film is added in the resin lens by pouring, so that the lens has a good adhesion property, and optical properties of the lens are not affected. The PVA polarizing film coated with the single monomer polyurethane binder is used to increase the adhesive force between the polarizing film and the upper and lower layers of the resin lens, and to avoid, in combination with a curing process, the falling of the PVA polarizing film.
