Anti-Blue Transparent Sticker

Great tool for optimising your current lighting at home. Or in car! This red version is intense. You're going for the best for pre-bed pre-sleep blue light removal. If your light source sucks, it will not make its spectrum better - remember that, it cannot improve the spectrum and light quality aspects of the light source (flicker etc.). But for the price, it's totally awesome. I have used it in our kitchen lamp that is active by night and it works well.

Great product. I've put it on the air conditioning's display, works like charm!
