Like most of us, I spend a lot of time looking at screens. I am looking at a screen nearly all day at work and I spend the majority of my evenings with the TV on. A couple months ago I kept noticing I was getting headaches at around 3 pm nearly everyday. The headaches were more of a nuisance than anything but they were affecting my quality of work. I began to wonder if these headaches were caused by digital eye strain, this prompted me to try some blue light glasses.
