PixelRo Universal Blue Light Blocking Screen Protector for 14 inch Laptop (16:9 Aspect Ratio) Anti-UV Eye Protection, Hanging Type, Reduces Eye Fatigue and Eye Strain, Sleep Better

Received a replacement and it fits perfectly on my HP Envy laptop. Screen detail is very clear. Installation for this hanging type was a breeze to simply hang. No 'bubbles' like on the other types I've had with the 'magnetic' sticky flimsy film. Very good quality and shipment.

Size measurements are quite accurate. Allow an extra 2 mm vertical to allow for the thickness of the protector, and measure from the very top of the screen housing (including the bezel) down to the bottom of the display. If the width is too much, just ignore it. Overhang on the sides doesn't matter much. Comes with a blue-light sensitive card and a blue light generator so you can test the protector out. Using that shows that the protector does seem to filter out most of the blue light. However, it is not clear that it filters out violet light which is an even shorter wavelength. I am using this on a Dasung 13.3" e-ink monitor that has frontlights that produce quite a bit of violet light. I used the Android app "Light Spectrum Pro EVO" to analyze the light spectrum from the monitor. On the cold light setting the monitor produces about 95% violet light. With the protector on, it still emits over 90% violet light. So, if the analyzer is correct (and it seem to be correct when I have checked the spectrum of many different lighting sources) then this protector doesn't filter out the violet light spectrum. If you are trying to get away from both blue and violet light, I don't think this does such a good job. What does work is to get some yellow cellophane and put that over the screen or on the back side of this protector. With that, the spectrum shifts entirely to green. No, the display doesn't look green, but it does look light yellow.Quality is excellent. There is protective film on either side which is easily removed. It might work for you and it certainly can't hurt. I'll try this for a while and then decide whether it would be appropriate for an LCD monitor, though you can likely get better blue-light reduction by using the Windows night-light setting and turning it on even during the day.

To turn on or off there is a single multi position button, push in then have to navigate to 2 different position with the button located in an awkward position on the right back side of the monitor where you can't visually see unless you turn monitor. Bad manufacturing to complex on and off for one button. One single operation button to turn on or off then when screen comes on turn to any other need with mouse.

I primarily watch moving screens, stock charts, slowly changing numbers etc. So my eyes tend to focus on a smaller area more often. This causes eye strain. It would become so severe that I had to stop looking at any screen for the rest of the day.Does this solve the problem? Well it does make the screen softer and more friendly to the eyes, however the real answer is lighting. You have to mimic daylight as much as possible, thats your real answer.Another fact is technically you can solve the light temperature using software, I use redshift and set the daytime temperature to 6000K and nighttime to 3500K. If I survive the day without eye strain, the night time browsing is very pleasing even without these filters. But during the day I definitely feel better looking at the monitor with these filters on.Overall, the filters are really good, well made and backed by Samsung.But if your lighting is bad dont expect miracles.I will keep using them for another week or so and then update the review accordingly.

This is the 3rd screen protector I bought from PiexelRo.I like its good screen quality/texture, nice packaging with anti scratch film on the screen protector and the overall well made feeling by the product.One thing to watch out is this screen protector hanger is ~0.5 inches thick. So it might not be able to fit a thick screen. Please measure well before purchasing.If it fits, it is great!

The item is 1st class, from the packaging to its quality feel. It does exactly as described, I can crank up my glossy HP monitor and my eyes are much less fatigued. It seems to give an accurate picture without excess yellow like some other bluelight protection screen. It is worthy of the Samsung backed name. Just one thing however it does not help with glare from room lights, it reflects just as much as without one. But thats the price you pay for having it so transparent looking. So I give it 4 stars for that. If your're 1st goal is Bluelight reduction this is the one.

It's easy to use, but it has glare.

I got upgraded to 2 screens and noticed my eyes started to really hurt even with Blue Blocker glasses on. The sides of my eyes would run water by the end of the day. I now have these on Both screens and no more tired or leaky eyes. Love!

Would not fit my 27 inch iMac mid 2011 PC the lugs on the top not deep enough to hook it over the back. Will only fit a screen 20mm thick or less. Had to saw off the lugs to get it to fit.Other than that it looks good and seems to filter the UV as far as I can tell. Need to increase the screen brightness a touch to get it to my particular liking.

I wanted a blue-light and glare reducing screen for my work monitor. I can't comment on this screen protectors' blue-light reducing capabilities, but it actually reflects more light than the screen I wanted to use it on so I don't know it what way it can be considered anti-glare. It does actually hang well over the monitor, so if you want more glare, then it's great. To me, it's worthless.

The screen was far too reflective and made matters worse, not only because it was reflective but also because it reduced the brightness.

I don’t know what happened but this screen cover has made my eyes totally relax

Really pleased with it, can't complain.
