Blue Light Blocking Screen Protector Panel for 23, 23.6, 23.8, 24 inch Diagonal PC Anti-UV Eye Protection Filter Film - Widescreen Laptop and Monitor Frame Hanging Type (W 21.2" X H 13.4") [1 Pack]

I bought this item to block blue and UV light emitted from my Dell laptop screen. The very first night after I installed it, I slept better than I have in a long time, and I have had improved sleep ever since. I have also had less eye strain since using this filter. Blue light is absorbed through the eyes and confuses the brain into thinking it is daytime. I am very glad I found this item. Now I can use my laptop later at night without worrying about blue and UV light affecting my sleep or my eyes. I highly recommend this item for blocking the blue and UV light emitted from backlit computer screens. The item was simple to install.

The screen fit perfectly and I used it two days. Today I bumped the corner and a triangular piece snapped off. It didn't take much to snap it.Update: I was sent a replacement promptly and it works great! Great product that I will be more careful with.

I am seeing a doctor for eye strain and was told to purchase a blue light block for my computer besides cutting back on computer time, duh. I bought the VINTEZ Blue Light Blocking Screen Protector Panel for 15.6 inch Diagonal LED PC Laptop Anti-UV Eye Protection Filter Film - Widescreen Laptop Frame Hanging Type (W 14.2" X H 8.7"). Easy to use as it just hangs over my computer screen. Easy. I can't seem to find anywhere though the percentage of blocking. I want as high a percentage as I can find, but not sure how effective this one is. It does allow my eyes to feel more relaxed, but at the cost of vision clarity. Gives a faded appearance which isn't too bad. Just different and less bright which is probably the purpose to begin with.As far as anti-glare, I still see the lights behind me and have to make sure that all lights are off to avoid seeing them on my screen. So, the anti-glare doesn't work. My eyes do seem more rested as the brightness of the computer is dim, which I could have adjusted myself. My main concern is if the blue light is being blocked. I can't find the percentage yet. If it is not blocking blue-light and UV rays, then I just waister $33+ . How would I know?

If you spend hours at the computer (like most of us these days), this blue light blocking screen protector is a small addition that can make a big difference. This screen protector is made for 20-22" monitors and fits like a charm over my 21.5" screen, hanging right on the frame. Just unbox it, hang it up, and you’re good to go!Pros:Effective Blue Light Blocking: I noticed my eyes don’t feel as tired after a full workday, especially compared to standard screen protectors. This one actually cuts down the eye strain, which is huge for me.UV Protection: Bonus points for added UV protection. You don’t think about it indoors, but that extra layer feels reassuring.Cons:Slight Glare in Certain Light: It’s not terrible, but depending on your room lighting, you might notice a slight reflection.Limited Size Range: Make sure it fits your monitor specs before buying.I’ve tried a couple of similar products, but this one hits the sweet spot with its solid blue light blocking without messing with screen clarity. Perfect if you want to keep eye strain low-key but don't want to mess with glasses. For the price, I’d say it’s a worthwhile investment if you’re glued to your screen as much as I am!

Great company! I ordered a wrong size and they sent me a replacement for free. The blue light screen worked great. My eyes doesn't hurt anymore even if I stare at the computer for long hours.

The screens work great. I have to say a lot for the customer service. They are great. I was going to return the ones that I bought for work because now work is supplying them. I reached out and they send new ones for the my monitors at home (different sizes). They worked with me the entire time and informed me of shippement and tracking. The customer service was great. I normally do not write review or give 5 stars, but they earned it.

I'm a graphic designer. Before this role, I was staring at screens all day to run reports in Excel. I'd notice at the end of a long day, I'd almost feel queasy? Tired?Blue light glasses helped, but I get annoyed having to wear glasses all day. I got this for my monitor at work and I will never work without one again. Total game changer.I don't use adhesive to stick it to the monitor, I let the top ledge sit on the top of my Mac (it also worked well this way on a Samsung monitor before it) and it stays put. I'm looking at screens all day, 8-9 hours solid, without eye fatigue or feeling flu-ish at the end of the day from it.It does change the color your monitor shows a bit--but being humans, your eyes adjust to it and compensate for the color shift pretty easily.Easy to remove and clean when needed, easy to reinstall. 100% recommend.

Looks good, works well. Couldn’t figure out how to get the bottom part to stick, otherwise 5 stars
