I am often up late at night watching tv, scrolling my phone, or playing video games on my computer. I had a different pair of blue light blocking glasses and I didn't notice much of a difference when I wore them. These, however, have made a noticeable difference in how I feel when getting into bed after wearing them. I don't know how to explain it, but I feel calmer, and my eyes don't feel as strained. In terms of the quality of the glasses, these are much nicer than the other glasses I had
