NOWAVE Screen Protector for Monitor/PC/Laptop. THE ONLY ONE that is Anti Blue Light and Anti Glare! Matte Film Prevents Glare and Visual Fatigue Display. Easy Application. No bubbles

I don't see any difference in blue light or glare. The product descriptions states two films are included, but I only received one. The item was marked as Prime, but it took 5 days to arrive. I ordered the 20", which it said there was only one left. Apparently there wasn't one left, because I received a 24 inch. The edges weren't cut very well in the first place, so I tried to cut it down to size. Cutting worked somewhat well, but the item was misrepresented in size, quantity, and delivery. As this really just seems like a protector like I would use on my phone to keep it from shattering, it does nothing for my computer screen. I needed something to block a glare and tone down the brightness because my screen sits in front of a window. I notice no difference in glare protection from my original matte screen, or blue light.

after using it now for several months my eyes are still sore and I still get headaches. easy to put on the PC screen and as described no air bubbles form. but the sticky tape shows through as dirty marks. would not recommend at this price.

Not very impressed to find that when i opened my package the instructions on how to put it on was in Italian, so I now have a bubbly screen as a result. I was testing it out for my company as I have a large number of employees that use laptops all day and want to invest in screen protectors for all. Now going to have to try out a different make! Very disappointed with the outcome, package was also missing screen cloth!!

It does it job very well ... it protects my precious eyes against the harmful "blue light".
