Review on 3 Pack Blue Light Blocking Reading Glasses: UV Protection, Anti Glare Computer Eyewear for Men and Women by Tyler Spencer

They work both as regular reading glasses and as blue light blocking computer glasses, but when you use them on a computer you want to be weaker behind the monitor than ordinary readers usually farther than you hold the book. If you're using them as tablet or phone readers, chances are you're good at your regular reading performance. The strength of 1.0 in my case is weak enough to be perfect for the distance to my computer monitor (I usually wear stronger readers). So I can wear them during normal work at my desk and everything is clearer and less tiring for my eyes. However, the blue filtering is just above average efficiency between the best pair I have and the worst pair I've tried. The total width from the edge of the lens to the edge of the lens is about 120mm, so they are too narrow for a wider face than usual. The overall width of the frame is only 135mm, so even medium-sized people can feel cramped. They're fairly tight and unforgiving, with no springs in the hinges. Similar in size and overall feel to cheap discount readers, but they have a blue electronic screen reader blocking filter, which is effective. Basically, you get cheap blue-blocking readers at the price of cheap readers.
