My eyes and head ache when I work at my computer for a long time. What can I do
VisionIt could just be your eyes. Make sure that you’ve had them checked and that you’re wearing any necessary corrective lenses.
Screen Glare The light you read by may be too bright for your computer screen. Try to dim the light, and if you need to, get a desk lamp for other work. Also, if possible, move your computer so you aren’t directly underneath a light fixture.
Screen and Head Position
You shouldn’t bend your neck when you read from the screen. That can cause headaches. Your eyeline should be 5 cm to 8 cm below the top of the monitor. The screen should be about an arm’s length away.
After a day’ s hard work, we need some sleep. During the sleep, the fatigue(疲劳) of the body disappears and recuperation(恢复) begins. The tired mind gathers new energy, and the memory improves.
Some adults require little sleep; others need eight to ten hours in every twenty-four hours. Infants(婴儿) sleep sixteen to eighteen hours daily, the amount gradually diminishing as they grow older. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under great pressure may manage on six to eight. Many famous people have little sleep. Napoleon Bonaparte, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.
Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total of more than twelve years. By that age you will also have developed a sleep routine: a favorite hour, a favorite bed, a favor
