Review on i-Deal 2pcs Anti-Blue Lights Tempered Glasses for iPad mini: Protect Eyes from Harmful Blue Light with Bubble-Free Installation by Paul Opoku

bought to filter blue light. Passed through easily enough. However, as another buyer said, there's no sign of blue light filtering other than a small sticker on the outside box that says "anti-blue". I tested it and it does NOT filter blue light. It's a clean piece of cheap acrylic. This is deceptive and harmful advertising when children should benefit from it. Back immediately.
