Anti Blue Light Screen Filter for 27 Inches Widescreen Desktop Monitor (Does NOT fit 27" iMac), 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.

These fit great, easy to put on, they do have a glare %, but if you have strategic light block behind you, you should be fine. I bought these b/c I wanted to fix my schedule (blue light affects me a lot) and these helped me change my schedule with in 3 days! I am quite impressed. I was skeptical that these would actually work, after using them, They WORK. I love them. Worth every penny. Anti Blue Light Screen filter for 22 Inches Widescreen Desktop Monitor, Blocks Excessive Harmful Blue Light, Reduce Eye Fatigue and Eye Strain

I am impressed my eyes don’t ache as much as they did before. I’m disappointed the glare is very distracting.

Seems to be working well. My eyes don't tire nearly as bad.

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.

I have so far ordered three (3) blue light screens and the first one (1) I ordered is 1 Inch longer (that is from Top to Bottom on the Monitor/screen) than the next Two (2) Blue light screens. Each screen I found out cuts out 50% of the blue light and so far I have three (3) screens on my monitor which at the moment I am still getting 6.25% of Blue light still coming through the Three (3) screens. As explained each screen will cut out 50% of blue light with each screen and I calculate that 6.25% by explaining it this way. I have turned off 50% of the Blue light using 'Night Light' in windows 10 and that gives 50% left of Blue light. Then the First screen will cut the blue light down to 25%. The next screen will cut the blue light down to 12.5%. The third blue light screen will cut down the blue light down to 6.25%. So I will be ordering in the future for this monitor at least another two (2) blue light screens which, the next blue light screen will get the blue light down to 3.125%, that will be the fourth (4) screen and the Fifth (5) screen will get the blue light down to 1.56%. Because I spend so much Time on the Computer I will probably order another screen which would be the sixth (6) screen and that would get the blue light down to .781% as I do spend a large amount of Time on the computer and I can still even as we speak feel my eyes being still effected with the blue light even after the Three (3) screens are in place on the monitor currently. I would like to order more screens for this computer and for the other computers but I need to say I like the screen best that has an 1 Inch overlap at the bottom of the monitor. I now have brought anotrher 3 Screens now having 6 screens and my eyes are blarry. You need 8 Screens to get tyhe Night Light down to .15%. Each screen you buy gets rid of 50% of the clare.

I am really impressed with my new screen. I actually had to get it twice, because the first was cracked really bad. I issued a refund on Monday and I got my 2nd one on Wednesday, so that was impressive. I was worried it may not fit my computer well because it's a skinny/thin modem. I usually have a hard time keeping my webcam to stay on it. But this holds on nicely and it even helps my webcam stay better because the top part is wider. It does have a bit of a glare, but I don't mind because my eyes hurt so bad before, that as long as it helps my eyes not burn with the blue light filter, I'll take a little glare. I'm happy I bought it!

If you are using the product at night there is no glare from windows. If there are no windows behind you then you will have no glare. This product literally changed my life, and I no longer have to turn my screen yellow in Night Shift mode which didn't really work all that well to begin with. My eyes no longer burn. I can stare at the screen for hours and nothing. Way better than glasses. I'm a huge fan and I really could not live without it any longer. As soon as I take it off my eyes start burning.

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.

These take no smarts to install and also fits our curved monitors (27 inch). Not sure how much difference it makes though but it's a "preventative" measure.

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.

J'ai acheté ceci pour protéger mes yeux parce que j'ai acheté un nouvel écran, et contrairement à mon autre écran que j'avais déjà, ce nouvel écran me fait mal aux yeux. Donc j'ai acheté ceci pour protéger mes yeux. Mais ça me fait quand même mal aux yeux. Si je le ferme et j'utilise seulement l'autre écran que j'avais déjà, c'est correct, mais le nouvel écran, il continue de faire mal aux yeux malgré cette protection. Il semble donc que si il protège les yeux, ce n'est pas une protection suffisante pour ce nouvel écran. Je ne sais pas c'est quoi que ça prendrait pour me protéger les yeux contre ce nouvel écran? Les vieux écrans faisaient moins mal aux yeux. Remarquez que ça serait peut-être pire sans ce protège écran pour les yeux... donc en fait, il aide peut-être, mais pas autant que cela serait nécessaire. Il a un autre défaut, il reflète beaucoup et donc on doit faire attention comment on le place par rapport à la lumière.

The filter comes with a test-kit of sorts which helps you see that it does, in fact, filter out blue light; that's great. The 27" filter I bought is also a very good fit for my 27" LG monitor. However, the previously-matte monitor has an incredible amount of glare/gloss introduced by this cover. Time will tell whether that's a deal breaker, but I suspect it may be.
