Review on 🖥️ 27" Widescreen Desktop Monitor Anti Blue Light Screen Filter: Reduce Eye Fatigue & Strain, Block Harmful Blue Light by Brandon Patterson

This blue light shield is perfect for my 21.5" iMac. You just clip it to the top of the screen on and that's it. I bought it because I sit at the computer all day and my eyes started to water and hurt. After turning on this screen the pain is gone but my right eye is still watery after I was on the iMac for too long Overall I think the screen worked and provided a safety measure to protect my eyes.
