Hi, I started wearing anti blue light glasses/computer glass few days ago, and now I can work longer hours and have much lesser eye strain. So, I would like to recommend you all to get one. Demonstration - The local optical shop also shows me the demonstration, a laser blue light won't pass the special anti blue light lens. I recommend getting them from a local shop as you could get fake lens when buying online, even the optical shop owner told me the ready made ones are usually fake ones, it have to be installed and made specifically which will take about an hour wait time, so get them locally. I bought it for $40 just the lens, and the goggles cost $5. Had I know about this before, my eyes would be much better today, and I would have been able to work much longer hours. Some people say they have some software that helps with their eyes, this is different, these glasses protects you from the blue light that you can't see, I don't know how these exactly work, but just wear it and protect your eyes. Stay healthy. Thanks.
