21-22 inch Anti-Blue Light Filter for Computer Monitor

This screen is great. No problems with installation, bubbles, dust, etc. like when using films. And it does reduce the blue light and glare. It fit my Dell laptop perfectly.

Excellent packaging, easy install, works great! Was concerned about the quality because of the expense but now can see why the cost is not less - great quality!

Works great, and stays put. Did you know that blue light is bad for your skin? Well, I didn't until I developed rosacea and my doctor asked me how much time I spent in front of the screen. I took the advice and bought this and guess what, my rosacea was better in a week. This is 100% a true story, so if you have a similar problem, try this product.

Love these screen covers! I ordered two and started using them right away. They are a thick, good quality material. The 'lip' at the top made it easy to add to my computer screens (and will be easy to swap out to new monitors in the future). The sizing of each cover was spot on. Also, after the first day of use I noticed a significant improvement in overall eye strain and fatigue - exactly what I was wanting. Both covers came with adhesives if I wanted to affix them permanently and also had a cloth for removing fingerprints. Great product overall.

Easy install. This screen protector does not stick to my 24 inch Dell monitor like a phone screen protector so easy put on or off without damaging monitor. I put on the mini tape provided around the plastic rim of the PC monitor so it doesn't fall off. I recommend putting stronger tape towards the top of the screen protector since it upside down "L" Shaped and hangs on the monitor. It does have glare or a mirror effect to it, so a space where sunlight doesn't hit the screen is a good idea. It also has a tint and you may have to adjust your brightness settings. I can use my PC for longer periods of time and eyes are not burning or itchy red-eyed while using it for this past week. No headaches appeared either which is a good thing!

I am amazed by the results, and I know that sounds like a fake review! I have terrible migraines. And in the past year I’ve really struggled with the computer triggering my headaches and nausea. Daily. Plus eye strain and difficulty focusing. From the moment I popped on these screen protectors. I felt the difference. It’s been over a week now, and I haven’t had any issues with headaches, nausea, or eye strain. My productivity is way up!

This screen is light enough for anyone to attach- it’s a great quality- highly recommend to filter harmful blue light out!!

The size worked for my monitors, they hang nicely from the tops. You even get a cleaning cloth. My reason for the 4 stars is that there is a nasty glare, these should be made in a matte finish which I believe would help to alleviate.
