As a graduate student and instructor, I spend a very, very large portion of my day working at my laptop and staring at screens. I don't wear glasses for sight, but my eyes are very sensitive to indoor light and sunlight. When I started grad school 4 years ago, I remember going home with headaches behind my eyes basically every single day, but for some reason I never thought about what could be done (aside from some aspirin).Ordered these glasses with some skepticism, and I've only had them a week or so, but I am extremely pleased with them. I really didn't think I'd notice much of a difference, especially at first, but it's like they eliminated this head/eye pain that I wasn't even aware I had anymore. I didn't actually realize how much my eyes "strained" until I started wearing them. Even within the first few hours, I was like "wow...my eyes feel relaxed and I didn't know that was a thing." I started wearing them at night as well, since I usually am either on a laptop, my phone, or watching TV before bed (I know, that's bad, but sometimes it's unavoidable). I don't know that it necessarily made me sleep better, but no headaches!They come with a pretty sturdy case, and a good wipe to clean them with. I have a pretty small head/face, and while they look a little "big" for my face, they don't feel big and they don't slide off. Plus, the point is to eliminate some light - why would I want small frames for that? They do not look yellow when you wear them, which is a plus for me. I'll update if I have any complaints, but for now - these definitely upped my quality of life, and as a grad student, I'll take anything I can get.
