It absolutely works. Since I got a Chromebook at work, my vision has been deteriorating, with blurry vision with prolonged use and double vision in one sitting. Since I put one of these protectors on my screen, I no longer have any vision problems. I appreciate this product and would recommend it to others with the same problem. I also had melanoma, so I feel more comfortable knowing I'm not exposed to blue light on a daily basis. Thanks for that but now I have less reason to complain about my Chromebook and I was curious as to why devices need to be replaced lol.
