GUMIKE Anti Blue Light Screen Filter for 20 21.5 22 inch, Universal Widescreen Desktop PC Monitor Panel Reduces Eyes Strain & Scratch Resistant Protection Filter Hanging Type

I liked the product. It helps me with eyes strain as I have to work all day on my desktop. I recommend it

I work from home and have 3 x 22" monitors crowding my desk. After a year of this, I one day rolled up my sleeve to take off the Covid vaccine bandage and noticed I had a tan line. Well, since I've been outside about 10 times in the past year, this didn't make sense. I also always had a sense of sunbird on my scalp - still, didn't make sense. Then I researched and learned that some monitors are putting out UV rays, among others, so even if you have the blue light blocking glasses, which I do, it will affect your skin negatively. So I researched different offerings and came upon these. I balked at the price but I needed them and they seemed the best. Well I wasn't wrong. Perfect sturdiness. Doesn't interfere with the detailed work I do. The packaging blew me away, they paid attention to every detail. Protection film, a little soft cloth to clean your monitor. Two of them I have cocked sideways, which won't work with the current bend/drape system, so I used a thick double-sided tape I saw on TV (sold here!) and stuck them on at the top. I feel such relief from the rays, I can't tell you - or I can and I am! Buy these! You won't regret it.

I received cracked screen, I do not have time to return back!

I purchased 3 of these and they all work great! I tested them with a blue light test strip and they do not let any blue light through. They do have a glare to them. One of my computer screens does not face any window, etc and there is very little glare. My other 2 screens do get some window exposure so there is a slight glare. When the computer is off, it is super noticeable, when it is on, it is not as noticeable. It is a slight annoyance but with the amount of blue light being blocked, it is definitely worth it!

I spend a good deal of time in front of this monitor, everything from editing photos, to watching how-to videos, to movies. The main reason I bought this was for editing photos. I gave 3 stars for glare because the overhead light behind me does glare on the screen and I can see myself sitting here (which it doesn't do on the naked matte screen). I gave it 3 stars on brightness because it does darken the image that I'm working with, and I need to see every subtle shade and color variation for proper adjustments. If I'm just watching a movie, or how to video, then it's fine, but as I said I wanted it for photo editing. Not that important is the hanging "installation" feature. My monitor has a somewhat convex top. It sits on there okay, but doesn't sit completely flat, although it does cover my true 22" screen perfectly. I ended up putting it on my wife's 19.5" work monitor since all she needs is information, and images aren't important. It sits perfectly flat on top but sticks out about a half-inch on each side and an inch and a half on the bottom, so she has to move it to access the power button. All in all, I'd recommend this, depending on what you need it for.
