Ergonomics Here are some guidelines for adjusting your display to reduce glare and to accommodate your physical size and shape. • Arrange the display so the top of the screen is slightly below your eye level when you're sitting at the keyboard. The best distance from your eyes to the screen is up to you, although most people seem to prefer 18 to 28 inches (45 to 70 cm). • Position the display by tilting it up or down to minimize glare and reflections on the screen from overhead lights and nearby windows. 45-70 cm (18-28 in.) Shoulders relaxed Forearms and hands in a straight line Forearms level or tilted slightly Lower back supported Thighs tilted slightly Top of the screen at or slightly below eye level (You may need to adjust the height of your display by raising or lowering your work surface.)
