I have a blue light filter on my glasses. I opted in because I sometimes use screens close to bed time for work.
I'm not going to tell you they work better then a placebo, but they work as good as one, and that's all I need.
They are 100% yellow tinted. Anyone who tells you they don't block blue light is a liar.
Same here, and I've tested it with a blue laser and the lenses block the blue laser almost completely. It's definitely a benefit to have the blue / UV filter coating on glasses. Another easy test is to walk outside in the bright June sunlight and look around with and without the glasses. The UV filtering reduces eye strain outdoors in the bright sun too, but obviously not as well as sunglasses.
