This screen protector is really, really good! I just installed it on my monitor on Friday and so far it has made a huge difference in the amount of blue light getting into my eyes. My eyes no longer hurt as much when I stare at a computer for more than 8 hours a day. Installation is a little tricky and it takes a long time to remove air bubbles as it is like installing a large phone screen protector, so you just need to be patient. Also, I love the product!
