那不要選Kindle Paperwhite,因Paperwhite也是發光的。應選舊款Kindle。
You don't understand. There must be light for you to read anything, right? The difference is direct light or reflective light.
Kindle paperwhite, etc is reflective light although the light is built in. The same way you read a paper book, we read with reflected light from the sun or from the living room light. In principle, it is exactly the same as you shrine an external book light on to a kindle lite.
For iPad/Nexus/Samsung Android pads, there is direct light. The screen of these devices is back-lit.
Easiest example is using a flash in photography. Using a standard flash on the hotshoe direct shrine on the subject, the photo has very harsh lit surface and shadow. If you use "bounce-flash" the photo appears a million times softer and more natural.
Standard flash is iPad/Android pad. Bounce-flash is kindle paperwhite. Guess which one is easier on the eyes.
Read Amazon's explanation of paperwhite for more.
