To some certain degree, reading on computer is worse that reading books. Pls note I do not mean that you can not reading E-book on computer; if you want to read on computer, you had better change the brightness of your computer less bright, which will be less harmful. According to the experts, your eyes are burning because you're basically focusing your eyes and staring at a light screen. Besides, you should not see the computer screen for long time, because this will make your eyes tired. I usually take breaks in between if I am working on something and reading a book on the internet. Otherwise, you will have the dry eyes and redness. If you can not monitor yourself to take breaks, then I strongly advice you should read the paper books, which is much better than E-books.
