[2 Pack]Nusign 10.2‘’ Paperfeel blue light Screen Protector ,Compatible with iPad 9/8/7 (10.2-Inch, 2020/2019 Model, 9th,8th / 7th Generation).Anti-Blue Light (Eye Care) Protection. Anti-Glare Matte Surface for Drawing, Great Sensitivity. Scratch Proof

So because they are cheap and they come in packs of two, My installation recommendation is, Take the stuff they give you to install the screen and throw all of it away but the screen itself and the card for getting bubbles out. Use your own lint free towel and glasses cleaner to remove all the grease and dust from the ipad. You will be throwing the first protector away so don't worry about being perfect with the dust, just make sure you get it clean, and mostly dust free. You will want to be in an area without a lot of air movement. Use the first screen protector as practice and apply it to the ipad, once you are comfortable with what you are doing,press the first screen protector squarely down, And get ready to do the second. When you peel off the first one it will bring all of the dust with it, and you can get a perfect no bubble matte drawing tablet,very comperable to wacom pads when they are new, in terms of friction.

It's blocking the blue light to great extent ..

This protector is not matte or paper feel at all. It is easy to apply and fits perfectly but my hand does not glide as it would on a matte protector which is what you need to draw or write more efficiently with the pencil.

Good Deal
