Amazon Kindle Touch, Wi-Fi, 6 inch E Ink Display – (X001E1J5KB) – RFB

Less eye fatigue:Every time your eye switches from a bright screen to a dimmer, ambient room, your eyes have to adjust, which may result in fatigue. With E Ink, the page is the same brightness as everything else in the room so there’s no adjustment needed.

Reduced glare:All E Ink surfaces are treated to be matte like a printed page, reducing glare and increasing legibility.

Read in any position:E Ink screens have a uniform contrast ratio that does not change with your viewing angle, so you can read in any position.

Sharp, clear text:E Ink screens have 100% aperture ratio, so there are no gaps between pixels. The blacks and whites on an E Ink screen are uniform, improving image quality.
