ZYY Diagonal 27 Inch Anti Blue Light Screen Protector for (W 24 1/8 x H 14) Monitor, Desktop PC UV Blocking Filter for Eye Strain, Hanging Computer Screen Blue Light Blocker 27 Inch Monitor

I really like this blue light blocker for my monitor, I have a curved screen and this design is perfect because you don’t have to apply anything onto the screen, it just sits over it, super easy to assemble, it’s held up with 2 small rubber “arms” that you put push into the pre punched holes. It’s a perfect fit, so if this is your correct size too, which for me, it is, you’ll love it. The screen itself has a slight tint to it, I guess that's for the blue light blocking, I don’t feel like it’s radically altered my colors and it doesn’t appear to be much darker. I’ve been using it for about 2 months now, and I think my eyes get less tired when I have to be in front of the screen for a long time.

I bought these because my eyes were really struggling after long days at the computer. I do wear glasses, but I forgot to add the blue light coating to my lenses this time around—so I needed something ASAP. These have been a game changer. My eyes are no longer sore after hours of computer work each day, and it really mutes the harsh lighting from my monitors. I also love how easy they are to install, and that they aren’t permanent. If/when I upgrade my monitors, I can just remove and reuse them (as long as the size is the same), so I’m saving money in the long run. Honestly, this makes it less of a big deal whether my glasses have the blue light coating or not. Highly recommend for anyone who spends a lot of time in front of a screen—glasses or no glasses.

Freakin life savers. Protected my monitors and they’re barely noticeable. Yeah, there’s a bit of reflection since it’s not matte, but the trade-off is worth it for the scratch and fingerprint protection. Not even four days after putting them on, I was working on a PC build and the side panel slipped and slammed into one of the monitors. Without this on, it would’ve either cracked the screen or left a massive scratch. The protector took the hit. There’s a small mark on it now, but honestly, I can’t even see it unless I go looking. Could probably buff it out with some car scratch nu-finish or something if I really cared. 100% recommend. Only real downside is they don’t make a curved version. Just for reference, it’s not a film, it’s a solid acrylic sheet that hangs over the monitor from the top. I don’t even notice it’s there most of the time.

It has been about 10 years now since I had brain tumors surgery and my head became very sensitive where any electronic devices affects my head. Cussing headaches, dizziness, disoriented, forgetfulness and so forth… There are so many to choose from and didn’t know which one to use. I decided to try this one after reading about the descriptions. So I would say about 80% blocks the blue light if that’s what was the cussed. Just let you know my case is severe case, and I think it’s pretty good for my condition.

It works!!! I have tried blue light blocking glasses that didn’t do anything but these computer screen blockers actually work! No more eye fatigue! I immediately noticed a difference. They were easy to install and they fit my monitors perfectly.

This was a good purchase. I work for about 8 hours in front of a computer daily and was starting to feel strain in my eyes. After starting using this a few months ago I stopped having this problem. It takes a few days to get used to the screen’s light as it is dimmer, but I got used to it pretty fast and I can see the screen totally fine. The screen holds up straight and it is easy to put on. It does have a little bit of a glare (reflection) but it does not bother me. Overall this has been a good investment to protect my eyes.

It does the job of removing glare and harsh blue light from my monitor. My eyes are no longer strained.

Reflection is obtrusive. The silicon feet don't hold well. I knocked it off twice yesterday alone by reaching behind it and now it is scratched. I think the blue light blocker is helping, my eyes don't fee as tired, but I am returning it.

Tardo un poco su llegada, la mica se ve bastante gruesa apenas la empezare a usar por lo pronto el tamaño quedo perfecto a mi pantalla y creo que filtra bastante bien

La pantalla es de mica gruesa, se percibe de buena calidad. Filtra muy bien la luz azul y eso es lo más importante. Pedí la de 27" para iMac. Es importante, una vez la compren y si la van a usar en iMac, envíen mensaje al proveedor para que la pantalla sea apropiada para iMac, pues las dimensiones pueden variar entre las distintas marcas de monitores. No se perciben reflejos de luces que se encuentren incidiendo sobre el monitor. Buena compra, buen precio y envío a tiempo.

貼るタイプではなく、掛けるタイプであること。

The eye strain has reduced and I don't have to wear glasses anymore. This is better than my eye glasses with blue light filter. The screen color also looks normal and not yellowish

Buen producto. Mi monitor es touch y pensé que era como mica adherible. Aun así, no me arrepiento. Protege muy bien la vista
