I received 2 screen protectors, there is a sticker on the front of the box saying it's a blue light blocker. I opened the package and used the blue light to check and no screen blocked the blue light. My return with Revane started immediately. In the attached images, the screen protector covers half of the blue light test strip and the blue light shines on it. The 2nd picture shows the end results and proves it doesn't block blue light.
