Attention
】
When you work with the computer or play computer games, you should
make your environment comfortable and properly arrange the positions of
your computer systems so that your body is in a comfortable and flexible
state. The following tips might help you:
Backrest:
·
Choose a chair that can support the lower part of your back;
·
Adjust the height of your working table and chair to the extent that you feel
comfortable and natural.
Legs:
·
Ensure enough space under the table to allow your legs to move more
comfortably;
·
If your legs can’t rest on the floor comfortably, please use a footrest.
Neck:
·
Set the computer monitor in the center of your front space. If you spend
more time on viewing the documents than on watching the computer screen,
you can put the document just in front of you and move the computer screen
aside a little bit;
·
Try to use a document holder on which the document can be placed close
to your eyes’ height;
·
Adjust the top of the computer screen to the height of your eyes. For users
with astigmatic eyes, the screen may be adjusted lower than their eyes. Or
they can consult with the experts on health to select eye glasses suitable for
working in front of the computer.
Eyes:
·
Set the monitor to the distance equal to the length of your arm and then sit
in front of the monitor;

Keep the monitor away from light source with dizziness, or use a curtain to
shade the light;
·
Clean the monitor and your eye glasses (if you wear them) regularly;
·
Adjust the brightness, contrast and font size to the extent you feel
comfortable;
