17. Reading a Computer Screen isHarder than Reading Paper

1. Books, computers, and e-readers (such as kindles) all have their pro's and con's. Unfortunately for reading, there's some pretty big problems.

   • Books
     • Books reflect light, does not tire the eyes, but also cannot be read without a light source.
   • Computer Screens
     • An image on the screen, although it doesn't seem like it, is constantly refreshing. This constant refreshing (in combination with the emitted light), is what strains our eyes.
   • E-Readers
     • E-readers similar to a Kindle Paperwhite use what's called "electronic ink" that mimics a book. This "electronic ink" reflects light and doesn't constantly refresh. In fact, in some of the newer models, they actually have a backlight that doesn't emit blue light so you can read at night without the strain.
