here glasses function for blue light blocking. 3 type blue light lens you can choose it. Although the concept of anti-blue light has been popular for many years, there are still many people who do not fully understand it. Only know or see that blue light pens are tested to filter harmful blue light. But don`t know how much to filter? How much is appropriate? It`s also blue light resistant and can pass the most basic card tests. It doesn`t prove that it functions up to par. This test is the easiest and useless. .According to our test, as long as it can filter 10% of blue light, it can pass the above test. So this test is useless. For clear lenses, at least 20% of blue light needs to be filtered to be effective. For people who work under blue light for a long time, some need to filter more than 70% of blue light. This can be achieved with the help of tinted lenses.The video below is a simple spectrometer testing process. Obtain three sets of data, orange lens, yellow lens, transparent anti-blue lens. We can see that are: 0.1, 23.5, 72.3. Indicates that only 0.1% of blue light can pass through the orange lens. Filter out 99.9%. The pass rate of yellow lenses was 23.5, and the filter rate was 76.5%. Clear lenses pass 72.3% and filter out 27.7%.please check this video.
