Review on COOSKIN Softness Protector Protection Blocking by Kyle Larjin

I was skeptical at first when I received this product as the packaging didn't say 'anti-blue light' and it was clearly blue compared to other dies The lightweight screen protectors I bought had a bluish cast. I decided to test if this works by using black light which has more blue light than your computer screen. In the first shot, black light shines on white paper with no protective film and you can see how blue it looks. I then took the black light and placed it on the screen protector and then directed the light onto a piece of white paper. In the second image you can see that the color changes from blue to purple. For me, this satisfies my test to see if it can block blue. It doesn't look like 100% blocking but I also tested it with the blue tinted protectors I had and I have to say that these protected much better. In general I am satisfied
