Embodiment Construction
[0024] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0025] The applicant analyzed and tested several existing manufacturing processes of polarized lenses and found the following:
[0026] 1. In the existing manufacturing processes A) and B), PC lenses are used, so the internal stress of PC polarized lenses is relatively large. refer to figure 1 As shown, it is the internal stress test of the polarized lens manufactured by the manufacturing process B). It can be seen from the test results that the polarized lens has a very obvious rainbow, indicating that the internal stress of the lens is relatively large.
[0027] 2. In C) and D) of the existing manufacturing process, nylon lenses are used. Although the performance of nylon lenses is higher than that of PC lenses, there are still some internal stresses. refer to figure 2 As shown, it is the internal stress test of the polarized lens manufactured ...
