Anti Blue Light Screen Filter for 21 and 22 Inches Widescreen Desktop Monitor, Blocks Excessive Harmful Blue Light, Reduce Eye Fatigue and Eye Strain

Ordered 4 of these- 2 for me and 2 for my co-worker as we both have 2 monitors each. They work great for what we needed. The strain on eyes was getting to the point of causing headaches. They fit on the monitors very well, we didn't even use the adhesive strips. There is just a little bit of a glare, which doesn't really show unless the background on the screen is dark. The quality of the panels is very good as well. It really does help with the blue light. I highly recommend these to protect your eyes.

Item arrived quickly in excellent packaging and condition. My eyes have felt so much better and not tired anymore since using this monitor cover. Seller is also very responsive in helping out with my inquiries and requests. The glare happens when there is sunlight through the window, but not during night time or when there is just little sunlight.

It arrived packaged well enough so it did not break and was easy to install. It came with instructions and a test card to confirm it blocks the correct blue light frequency.

The glare has been pointed out in other reviews. Otherwise, I am happy with it and the fit is excellent. It has stay exactly where I first put it.

I bought the 24" screen for the 24" LG UltraFine 4K Display sold on the Apple website that is specific for Mac. The fit was perfect and it was super easy to hang. My webcam sits on top of it with no problem. I hope it does filter harmful blue light; no way knowing for sure that it does. That blue light emitter included still showed some blue light coming through the screen. The screen is a glossy finish so it does cause some glare, but this is not a big deal. The colors and picture come through clearly. Overall, I would still buy just for the reduction in harmful blue light.

The filter is more reflective than my monitor's screen. Reflections can cause tiredness due to focus issues. I contacted the vendor, and they said would be ok to attach an anti-glare directly to this filter. I still highly recommend this filter as, even with more reflections, my eyes are no longer sore at the end of a 10-12 hour workday. I was blown away as didn't think anything would really help, especially with such a simple solution.

Sized as described, unlike some other Google translated products on offer. Easy to install, and blocks blue light as advertised.

This filter creates new problems with glare that are as bad - or indeed much worse - than any blue-light issues it is made to fix. 99% of modern monitors have some form of glare reduction with a matte screen surface, so many buyers (like myself) may be unaware that a potential glare problem even exists. This product is glass-smooth, however, and it reflects EVERYTHING. First photo shows my monitor asleep with no filter. Second is the same shot of the monitor with this filter in place ["Anti Blue Light Screen Filter for 27 Inches Widescreen Desktop Monitor" $49.99; average rating "4.4"]. Third photo shows the filter covering the right side only. I cannot imagine a situation where this would be acceptable unless it's on an antique CRT with a fully-reflective/glass surface.Spend a few bucks more for the same style filter with blue light AND glare protection: the glare reduction may not be much better than what your monitor already provides (there are plenty of user complaints about that), but it won't make the glare a hundred times worse - like this one.(I'd have given this a top grade for fit except that it does not quite reach the bottom of my 27" diagonal screen. I don't think that's a major problem but dust accumulation and distortion might be future annoyances.)

I ordered a couple of protectors and they came with a blue light and a card, once you shine the blue light on the card it darkened, when I tried shining through the protector very little darkening. I am very happy with the quality of this product. I am going to buy for my wife's computer now.

Great product. All the others require that you stick a film to your screen which I don't want to do. It is clear, cuts down bluelight and definitely feel the positive benefits after 2 days. Just make more sizes! One for a 43" monitor for example!

I Used to have a headaches and blurred vision after spending hours on my computer everyday for work, but after purchasing this screen filter, I no longer have those problems. It installs very easily, just hang it on top of your monitor and it's ready to go. I highly recommend this product.

Good

If you like to look at yourself instead of the screen then go for it. Even though it blocks blue light well, it made my matt finish screen reflective.
