Kindle Paperwhite is one of the best e-ink e-readers around. It picks up where the Kindle Touch left off. It not only has a touchscreen display but comes with a lighted screen. Since you will be touching your Kindle’s screen to interact with it, you are better off picking up a screen protector for it:
Tech Armor Kindle Paperwhite HD Screen Protector: a high definition screen protector for the Kindle Paperwhite. It keeps dust and scratches away from your e-reader’s screen.
BoxWave ClearTouch: a pretty affordable and decent screen protector for your Kindle Paperwhite. It reduces 90% of UV rays caused by reflected light, protecting your eyes. A crystal version is available.
GreatShield Ultra Anti-Glare Screen Protector: works for the Kindle Touch, Kindle Keyboard, and Kindle Paperwhite. It can be removed and washed without leaving a residue.
There are a few other screen protectors available for the Kindle Paperwhite. We have had the most success with the above products though.
