(1) For most of us, much of our time is spent sitting at a desk and staring at a computer screen. (2) We do homework, chat with friends, or load photos on social networking sites in front of a computer. (3) All of that sitting and staring is not very good for our bodies or our eyes. (4) The easiest thing to do, but the one most people forget about, is to take breaks. (5) This means getting up from the computer for at least 10 minutes per hour to give your eyes a good rest. (6) Finally, sit with your feet flat on the floor or on a footrest, with your thighs parallel to the ground. (7) This stance will support your body, which, in turn, will support your head and neck. (8) The second thing you can do is to make sure you are sitting 18 to 22 inches away from the screen; the screen should be at your eye level. (9) If you do these small things, the hours you spend at the computer will be more relaxing.
