This works great - I got a new laptop at the beginning of 2020 due to the work-from-home situation and was finding myself spending more time (even at night) working on it than I meant to. Eventually my eyes were feeling "sore" and after doing some research it sounded like eye strain. A friend of mine recommended Ocushield after having some success with her iPad cover, and I was pleasantly surprised to see it on Bestbuy! Bought it, arrived in 3 days and got it installed that same night. It's been a couple of weeks now and the "sore" feeling on my eyes has gone away - not sure about the better sleep part, but I know my eyes don't hurt.
