Abstract: The present invention discloses a photochromic resin lens with a refractivity of 1.50 and a preparation method thereof. The lens comprises a resin monomer, a photochromic organic material, an initiator, an antioxidant and a photo stabilizer at a weight ratio of 100:0.01-0.1:1-10:0.1-0.9:0.1-0.9. The resin monomer is a mixture of a monofunctional acrylate, a difunctional acrylate and a tetrafunctional acrylate at a weight ratio of 10-80:10-50:10-50. In the present invention, a low-refractivity photochromic resin lens with a refractivity of 1.50 and an Abbe number of 58 is prepared. The lens does not contain toxic materials, is safer and more environmentally friendly to wear and produce, and has high Abbe number, clear imaging, high visible light transmittance, and high product pass rate. The visible light transmittance under UV irradiation is less than 20%, the color is deep, and the photochromic effect is good.

Abstract: 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.
