42-43 inch Anti-Blue Light TV Filter. Blue Light TV Screen Protector Panel (38.2 x 22.4 inch). Blocks Blue Light 380 to 495 nm. Fits LCD, LED, 4K OLED & QLED HDTV Displays

I tested the protector with a blue light beam and it works great – it truly reduces blue light but at the same time preserves the colors and the quality of the picture. I often work late at night and I have noticed that after installing the protector my eyes feel better and I fall to sleep more easily. So it truly preserves the circadian rhythms.My item arrived fast and it was securely packaged. The design of the item is great – it is very stylish and easy to install. Also, the protector prevents my screen from dust and scratching. Strongly recommend to everyone!

This monitor screen cover is better than I thought!! Well packed. I just placed both of them on my 2 / 24 inch monitors. Has a lip and you just lay it on the monitor. Has a cleaning cloth and velcro tabs if you want to use them. I did not need them. This was my first day today. Without them you can tell the difference with bright blue light. With them it’s like ... ahhhhhh. My eye doctor told me this will help prevent eye damage to cells in back of your eye. Just buy it. I am buying them for all my immediate family members. And telling other family and friends to buy them. I will tell you about the glare. One of the computer programs is dark grey/black background. I see alittle glare but I don’t notice when I am working. No big deal at all. When I am in other programs with normal backgrounds, no glare. Love these!!! Update: have used now for almost a week for 8-10 Hours a day at work. Still love them. I wanted to add I swear I am falling asleep right away at might. Another great benefit!!

Very well packaged, super easy to install and works great! Takes that bright glaring TV light away so it’s easier to wind down and sleep.

This was packaged very well. It did offer some dimming quality to our bedroom tv but I do wish the brightness was a little less harsh. I suppose i am sensitive to brightness in a dark room. This certainly helped reduce eye strain but it is difficult to gauge how much bluelight has been reduced. It straps around the tv nicely and does not affect visibility. Overall, pretty good, but difficult to weigh its value.

I was amazed at how better the picture was on my eyes. I'm developing cataracts and brightness wasn't good at all. I lowered it through the TV by 50% and with this shield to eliminate more blue ray, my eyes don't water as much and there's less strain when binge watching. It's a great piece. Attaching it to the TV was a bit awkward, but I managed to secure it well. With grandkids 3 and 5 I didn't want it to be able to come loose with them around and managed that after some doing.

I sit in front of the computer 8+ hrs a day and my eyes used to tear and hurt a lot. I also used to get double vision. But not anymore. This protector saved my eyes and my job! After just 3 days of using the screen protector, I didn’t have double vision anymore and my eyes felt good. This is a major win for me given the fact that I got LASIK eye surgery for my myopia six months ago. As stated - this monitor screen protector does not filter out 100% of blue light, but it worked great for me. I gues this is the reason picture looks good and I cannot tell any major change in colors.

It's a less expensive bule light filter that works. I have it on my 24 inch ViweSonic monitor and it's working just like the other ones I bought. I did not use the adhesive though. That give me the flexibility to use it on another monitor if needed. Thus far, a satisfying purchase. I would recommended it.

The glare seems worse with it on and there is no privacy effect. I'm returning it.

May have a glossy effect on the screen Couldn’t peel off any sticker off the screen to see any non glossy effect Perhaps not so much worth the price they have charged
