I've worn blue light blocking glasses for years, since I spend 80% of my day in front of a screen of some sort between work and home, and these are some of my favorite glasses that I have owned. They look great on me and they definitely relieve the strain on my eyes from staring at a screen for most of the day. The few times I've accidentally left them at home I always end up with a headache at the end of work. Will be buying another pair to leave at work to prevent this for sure.
