Poligraf asks: "All of slashdotters spend a lot of time in front of monitors. What are you doing to preserve your eyes? My issue seems to be not a declining vision, but fatigue after certain amount of time in front of the computer. It becomes so bad that I need occasionally to leave the room with computer and sit or lie down to relax for 5 to 10 minutes. What do you think of a full spectrum lights? Certain scientists swear that it is the best thing since sliced bread, others viciously rip their claims apart. Has anyone used these? What is your experience? What other methods can you come up with?\"
