Review on 🔵 Enhanced Blue Light Blocking Screen Protector Panel for 20-22 inch LED PC Monitors - Anti-UV Eye Protection Filter Film - Widescreen Frame Hanging Type (W 19.3" X H 12.5") by Alex Reunion

Even with the blue screen filter, eye fatigue continued to occur. Then I noticed that Windows 10 has an option to filter the blue light on my screen. I enabled this option and the screen color immediately changed to yellow and white. It wasn't the color at all that the blue light filter I bought produced. Thanks to the built-in filter in Windows 10, eye strain was reduced immediately. I suggest you find a way to test these filters after purchase. This one didn't suit me. Pros: It was well protected, in excellent condition and fit my flat screen. But my other flat screen has a slight bevel at the top so it doesn't fit this screen.
