Nice. The article also mentions BluTech lenses (BluTech LLC, Alpharetta, GA). I've found the marginal utility of bluelight blocking solutions are very context specific, indeed. And mostly-completely bahokie garbage, sadly, but not when it's BluTech and BluBlocker. BluTech/BluBlocker for the screen-induced fatigue is the correct solution. I always get BluTech HI Indoor AR pucks for my prescription lenses. And just switch to prescription sunglasses when I go outside.
