Anti Blue Light Screen Protector for HP EliteBook 440 445 G9/G8/G7/G6/G5, EliteBook 640 645 G10/G9, EliteBook 840 845 1040 G8/G7/G6/G5, EliteBook 745 (Not Fit 840 845 1040 G9/G10/G11, 640 645 G11)

I don't know about the blue light blocking, but it will keep the screen clean and damage free in the shop. There's no glare from the overhead lighting, the touchscreen still functions perfectly. Very nice product.

does not fit in even thought it says it does

You have to take your time placing it on your computer screen. Best to put it on your screen while sitting at a table. This way you have better control. If you follow the directions you should be fine. Love the blue tint and makes everything brighter.

Fitnent is totally off… does not fit my entire screen and the size is totally off

This is a good product. They even include a tester so you can practice before installing the actual one.

My first time trying this product and it's excellent. Will buy again.

After so many attempts at removing air bubbles, filter no longer adhered to the laptop, so I ended up removing it after only 2 days of use.

Very hard to put on and once I finally got it I realized it was off a little and kept bubbling up on the edges. The edges are not straight and it will never fit!
