Hack Of The Night : The 20-20-20 Rule
Although my job is behind a microphone, it's also behind like 15 computers. Ok maybe not 15, but for real, at least 5 screens. Maybe you work at a computer too, and know that after a while your eyes can get a bit strained and sore. Maybe you even get headaches from staring at them for so long. Try the 20-20-20 rule and see if it helps you out.
