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!

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.

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.

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.

As adverised. My sleep improved sharply after this purchase.

This Anti-Blue Light Filter is absolutely wonderful. It is so easy to install, all you have to do is sit it on the top edge of your screen. It does come with velcro tabs if you need a more secure hold, but for the office I don't need them. Right away I noticed a reduction in glare and squinting. It does have a slight tint but nothing interfering, I didn't have to adjust the screen brightness at all. Overall, this is a wonderful product and great value for the price! I highly recommend it!!

I recently added a blue light filter to my desktop monitor, and it’s been a game-changer. The filter was easy to apply and fits perfectly on my screen without any issues. After using it for a few days, I’ve noticed a significant reduction in eye strain, especially during long hours of work. The screen still looks clear and sharp, but the warmer tones make it much more comfortable to look at. It’s great for late-night sessions too, as it helps minimize the harsh glare and reduces the impact on my sleep. Overall, this blue light filter is a simple but effective upgrade for anyone who spends a lot of time in front of a screen.

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
