Review on 👁️ Amazon Basics Privacy Screen Filter - 22 Inch 16:9 Widescreen Monitor: Anti-Glare & Blue Light Filter – Enhance Visual Privacy and Reduce Eye Strain (22 inch (16:9), 18.76" x 10.56") by Daniel Mettler

I wouldn't say it's perfect, but it does the job. If you want bright colors it will be a bit dull and washed out, so maybe not very suitable for those who make art or graphics for a living. However, the privacy is really great. I also like its blue light blocking properties. I will say it wasn't the easiest setup but I was able to get it working and staying. My biggest gripe with this is that I had to use tabs to put it in place because things like dust can get stuck behind it and even a bug gets stuck in it so it still results in a lot of cleaning to be done inside and out. I haven't tested this on a touchscreen, so I can't comment on how well it works with it.
