Embodiment Construction
[0045] Such as figure 1 As shown, the high color contrast spectacle lens includes a substrate 1 and a strengthening film layer 2;
[0046]Substrate 1 is prepared by mixing and processing high molecular polymer, dispersant, solvent and ultraviolet absorber; wherein high molecular polymer is polyamide (PA), commonly known as nylon, or polycarbonate (PC); dispersant and solvent are Disperse Violet 26 (CAS No: 6408-72-6), Solvent Blue 97 (CAS No: 32724-62-2), Solvent Violet 36 (CAS No: 61951-89-1) and Solvent Green (CAS No: 128 -80-3) mixture, the content of disperse violet 26 is 40%, the content of solvent blue 97 is 30%, the content of solvent violet 36 is 20%, the content of solvent green is 10%; the ultraviolet absorber is UV- 531;
[0047] The ratio of high molecular polymer to the mixture composed of dispersant solvent is 1000:0.06~0.09; the ratio of high molecular polymer to ultraviolet absorber, polyamide (PA) is 100:3~5; polycarbonate (PC ) is 100:0.3~0.5;
