Adjust the angle of the screen and position of light sources in the room
to remove reflections. Avoid wearing light colored clothing and bright jewelry
which can reflect on the screen. Adjust the screen contrast and intensity
for greatest comfort.
Sit in good (not rigid) posture with both feet flat on the floor, lower
arms and thighs parallel to the floor. To achieve good posture you need
a chair that provides proper support and height.
Adjust Working Conditions
Keep your computer monitor directly in front of your face and below your
line of sight. Reduce the lighting in the room and use a desk lamp to illuminate
your papers. Angle the computer screen to eliminate reflections from overhead

Look across the room at a distant object every 15 minutes. Wear dark colored
clothes to minimize reflections.
