I am so grateful for these glasses! I got a severe concussion and nothing was helping, and cheap blue light glasses were not cutting it because I still had to work on the computer for around four hours a day for my remote job. These have helped so much! While recovering from the concussion, I would wear them all day and it stopped my headaches and helped me feel a lot better much faster so I’m very grateful for them. I’m not a huge fan of all the framing options that they have because I feel very Tony Stark as a young college girl wearing them all day lol, but great product!
