Blue Light Screen Protector for Laptop and (25-27 inch) Monitor: Protect Eyes, Reduce Fatigue (Accelerated by Samsung)

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.

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 does exactly what it is supposed to do and fits my computer perfect. Helps my eyes from burning and drying out. I will be buying another for my daughter. Very satisfied with the product.

Not sure what exactly happened, but when I opened it up it had a blue tint, I have bought similiar products and they had black / grew tint to them. I thought maybe it was just a different product. So I started using it, after about two weeks, my eyes hurt so badly. I have to use computers for my work, and at the end of the day my eyes felt like they were bruised underneath of them. I stopped using it all together, and a few days after I stopped using it my eyes felt better. I don't wear glasses when working on the computer.

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.

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!

El tamaño de el protector de pantalla es 22 pulgadas y yo la quiero 24 pulgadas... la caja es 24 pulgadas pero la caja noe sirve como protector de pantalla... así que no me sirve el pedido... todo estaría bien si el tamaño del protector de la pantalla fuera de 24 pulgadas como dice que es

Los protectores están bien, se ven bien, con buenos acabados pero el empaque a veces se queda pegado a los protectores y cuesta trabajo quitarlo.

Screen cuts out all blue light and gives you a testing light and strip to show its effectiveness, works

Bon produit, discret et bien adapté. Se nettoie et s'installe facilement.

Keine müden Augen mehr am Abend, mehrere Kollegen haben sich zwischenzeitlich auch diesen Schutz gekauft

Funciona bien, pero cuando el fondo es oscuro te reflejas en el portatil.
