After peeling off the original light guide, replace with any common anti-glare PET screen protector
You may get a matt screen guard designed for kindle. But this one I got lower the resolution of the screen, i.e. the text became less clear.
I then tried another anti-glare iPad PET screen protector. Cut it into Kindle's size. This one does not lower the resolution, but the anti-glare effect is not as good as the original light guide.
