Review on MOSISO 20-22 inch Computer Anti-UV Eye Protection Filter Film with Blue Light Blocking for Diagonal 20, 21.5, and 22 inch 16:9 Widescreen Desktop PC LED Monitor Panel (Dimensions: 19.29 x 12.48 inch/L x W) by Tony Miller

The screen has been badly scratched (probably after many returns) and does not sit close enough to the monitor screen for the text to be easily read. I have to manually press the screen against the monitor screen to be able to read each letter clearly, or I get a "blurred" image of the text, which is eye straining and defeats the purpose of this screen in the first place. Not a very good design, it's a piece of expensive transparent/opaque plastic film, nothing more. I'm scratching my head at this point and will be trading for something better, something that doesn't come with scratches everywhere. For $50 that's a shame!
