Ive had them only for a few days but it seems to be working well so far made of fairly brittle cheap plastic which resulted in them breaking after 1 month nice and light frame i should have expected from the price tag but it is poor quality

My son raved about his blue light blocking glasses so i decided get a pair for myself because i sit in front of my computer all day for my job and had been having migraines and difficulty sleeping even though i was tired
