Bought this to block blue light. It didn’t block the blue light. Screen looks exactly the same. I have anti blue light glasses so i can tell the difference. If you need a good screen protector for cheap this is it. Easy application.Horrible. Frame doesn’t help at all to put on. Ended up having to remove it to get it completely on. Then adhesive side gets dirt on it so fast won’t come off and stuck on the screen. Bubbles won’t go away. This is why I hate screen protectors.
