ultraviolet blocking after the samples (examples 1 to 6 and comparative example 1) were completed using a plano lens with a center thickness of 2.0mm, the ultraviolet blocking was measured in a carry4000 apparatus, and the specific results are shown in table 9;
(2) Yellow index YI:
yellow index test a flat lens with a center thickness of 2.0mm was selected, and after the samples (examples 1 to 6 and comparative example 1) were completed, the yellow index YI was measured in a Carry4000 apparatus, and the specific results are shown in Table 9;
(3) Chromaticity values L, a, b
The chromaticity value was measured by using a flat lens with a center thickness of 2.0mm, and after the samples (examples 1 to 6 and comparative example 1) were completed, the chromaticity value was measured in a Carry4000 apparatus, and the specific results are shown in Table 9;
TABLE 9
| Project | UV blocking/nm | Yellow index YI | L | a | b |
| Example 1 | 407 | 3.24 | 95.00 | -0.16 | 1.30 |
| Example 2 | 407 | 5.12 | 95.73 | -0.31 | 2.39 |
| Example 3 | 406 | 3.65 | 94.96 | -0.24 | 1.60 |
| Example 4 | 405 | 3.26 | 95.10 | -0.17 | 1.38 |
| Comparative example 1 | 408 | 5.84 | 95.36 | -0.41 | 2.79 |
2. Conclusion:
(1) Example 1 compared with the comparative example, the new ultraviolet blocking agent 2 can achieve 407nm ultraviolet blocking, and the yellow index is reduced to 3.24, so that the bottom color of the lens is relatively shallow, and the ultraviolet blocking agent is the optimal scheme.
