New studies have show that it does not. Even watching the tv too close which used to be thought to ruin your vision has been proven to not be true either. Its only temporary and will not ruin your vision or make you blind.
Too much strain on your eyes can cause nearsightedness. Mine has worsened from spending a lot of days in front of the computer and studying in front of my books.
