Review on 🖥️ Premium Privacy Screen Filter for 27 Inches Desktop Computer Monitor: 16:9 Aspect Ratio, 23.54" x 13.27" Size, Anti Glare & Anti Blue Light Protection by Alex Britton

The screen operates at a 45° angle and blocks all visible information on my 27 inch curved monitor. It has a matte side and a glossy side. The only downside is that the screen appears to be curved towards the matte side. Attaching the matte side up is a problem. Costs $80 though, don't see the point in spending $150 or more.
