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 Fock Dean

I ordered this for my desktop as I now use it all the time for online classes. My Mac desktop is older (2011 model) so it's thicker than the screen hooks. However, this does not affect the coverage in any way. It still falls well below the edge of the screen. Overall I'm happy with it - fast shipping overall and it's not damaged or scratched at all. The cling film did its job and protected the surface. The glare is no different than what my regular screen gives me. With the current settings in my room, I have a window behind me and it doesn't reflect any more than it did before. I quickly checked that it really was blocking blue light and as soon as I took it off the screen I saw a big difference. Worth the money spent to relieve eye strain.
