摘要： 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.
