Blue Light Blocking Screen Protector Panel for 23 and 24 inch Diagonal LED PC Monitor (W 21.06 X H 13.78 inch)

Definitely not one of the cheaper ones out there but I love it. My eyes are not even tired anymore. Cuts down the glare and the blue light for sure. Screen does appear a little darker.

I'm a software developer and constantly staring at screens for more then 8 hours a day. After COVID stay home restriction happens, I have to use my own computer everyday, which has 3 monitors, 23.8 inch each. After a while my eyes just feel tired and sensitive to lights. That's when I realize I need protections for my eyea from all the lights emitted from the monitors.This blue light screen protector appeared to my search and got a very good rating. They are built with quality and easy to install - just put it on your monitors.After using them for a while, my eyes feel relex and I can tell the lights emitted from the monitors are not as 'sharp' as before.Highly recommend!

Really makes reading on a monitor easier on the eyes. My eyes are a lit less fatigued and I love that I can just place this on top of tha monitor. No peel and stick fussing. Perfect.

THIS SCREEN PROTECTOR WORKS AS STATED. BEFORE I PUT IT ON I COULD ONLY BE ON MY PC FOR ABOUT 45 MINUITES BEFORE I GOT EYE STRAIN AND OFTEN A HEADACHE AND HAD TO TURN IT OFF.NOW I HAVE SCREEN PROTECTOR ON I CAN WATCH FOR HOURS WITH NO EYE STRAIN, SO THE BLUEFILTER WORKS. I GIVE IT FOUR STARS BECAUSE OF THE REFLECTION FROM ROOM LIGHTING BUT I WAS ABLE TO CURE MOST OF IT BY PUTTING A SMALL TABLE LAMP BEHIND THE MONITOR AND TURN OFFTHE OTHER ROOM LIGHTS.

I think the blue light filter is working, only had it for a day but I noticed less strain on my eyes when using the computer for more than an hour at a time. Could be a placebo effect, so I will keep using it and update later.One thing about these filters: the glare on these screens is really really noticeable so if you have a light or a window behind you it will turn your computer screen into a mirror. For now I just use it at night or in darkened rooms, but it would have been nice to have a matte finish for these (funny because I go out of my way to buy matte LCD screens due to the glossy displays giving me headaches). I guess if they do filter out the harmful blue light then it is worth it, but if it also eliminated rather than added to screen glare I think this would be a much better product.Update: Having used for nearly a year now, I would say overall it has significantly reduced eye strain and headaches associated with staring into a computer screen all day. Still wish they had a matte version of the screen protector, as I type this I can see my fingers in the reflection...and it is night time!
