Kindle uses an electronic ink screen that looks and reads like real paper. The matte screen reflects light like ordinary paper and uses no backlighting, so you can read as easily in bright sunlight as in your living room. Unlike tablet screens, Kindle has no glare. Kindle also has the advantage of significantly lower power consumption than tablets. Kindle does not require power to maintain a page of text, allowing you to read for up to a month on a single charge, with wireless off and a half hour of reading per day, versus hours on a tablet or smart phone. Every time your eyes switch from a bright screen to a dimmer, ambient room, your eyes have to adjust, which may result in fatigue. With Kindle the page is the same brightness as everything else in the room so there's no adjustment needed. With Special Offers included, you can shop while you use your Kindle E-Ink.
