MOSISO 20-22 inch Computer Blue Light Blocking Screen Protector Anti-UV Eye Protection Filter Film Panel for Diagonal 20,21.5,22 inch 16:9 Widescreen Desktop PC LED Monitor(19.29 x 12.48 inch/L x W)

I used a blue light tester to make sure it really worked, and it does! Very well! My employer ordered two blue-light filters for my two work computers. They paid $90 each. I tested those as well. They DID not block the blue light. I'm going to see if my employer will let me return those and purchase these. If they refuse, I'll purchase two of these myself. I was flabbergasted when I ran the test on the two that the employer ordered. I also tested my eyeglasses that are supposed to have blue-light protection. Guess what! They didn't work either. I would highly advise everyone to purchase a blue-light test kit. They are very inexpensive here on Amazon. You will be amazed at how many fakes are out there, but rest assured, this screen protector is not a fake!

Easy to use, easy to clean. Definitely helps protect my eyes and has helped my migraines tremendously! A little pricey compared to other products but worth the extra cost. I would recommend using, especially if you have work from your computer a lot!

Fit perfect much much easier to work on my computer with way less glare. My eyes worked much better as the day went on, with reduced fatigue.

One senses manufacturing pride in the design, manufacture, quality control, care of clarity of accompanying instructions and customer-cetnric packaging of this product. The look and feel of my two monitors got an instant 'touch me gingerly' kind of ambience around them. Highly professional super professional industry grade and simply gentle to the eye. Great ease of installation. A four (4) year old, given the screen after unboxing, will mount the screen over the monitor in under 6 seconds ( not 6 minutes- seconds -no sticky gluey stuff to paste, just hang!) Quality accompanying screen cleaning flint cloths. The color is so inviting and gentle to the eyes ( I'm aware I'm repeating this critical success factor but it worth emphasizing, not repeating)..

Seems to work well. No glare!

Really easy to put on and covers screen well. Like that it is just slide on. It immediately helped my eyes not feel so strained. The only drawback is it does cover my computer screen on/off button. I just moved the protector over to be able to access the button.

I made sure to measure my screen and it is a perfect fit, only a bit long on the bottom but not really noticeable. It is indeed very reflective but I do have lamp shining directly behind me. Overall, it fits the purpose since I needed to create a cover for my screen than the blue light protection since I have nightlight in my windows setting already. No scratches. Update: The screen does scratch easily so becareful how you're cleaning it.

If you ever worked in front a computer for 9 hours a day. This is a great find and buy. No more dry eyes, double vision, and headaches. After one day of use I knew this was the best thing ever. I would recommend this to everyone.

Se coloca perfectamente y protege, me ha encantado

Me parece un excelente producto y cumple a la perfección lo que promete. He tenido que trabajar por muchas horas frente a la computadora y con este producto mis ojos descansan mucho. En mi caso lo compré para una iMac viejita, la pantalla es un poco más gruesa y no encaja bien el producto (ver fotografías), pero lo solucioné con una “mexicanada” (cinta adhesiva), porque no quería devolver el producto ya que me pareció excelente. Lo evalúo con 5 estrellas por el que producto es excelente, solamente sugiero revisar el grosor de la pantalla para la que lo van a utilizar.

This screen has made a huge difference to my eye strain after a long day of computer work.

I have blue light damage to eyes so bought this years ago, love it, so bought another one, the price gone up a lot. But my eye sore and fatigue are gone. It is much better than the thin film ones with sticky edges, i have both and much prefer this one. It doesn’t cure up and trap bugs like the film ones. And it can be easily moved to use for different devices such as computer screens and tv. Maybe not for laptop and this is still a fragile product and need to be handled with care. I use sticky film one for laptop.
