take  short  rests  to  relax  your  neck and  shoulders

avoid  tensing  your  muscles  or  shrugging  your  shoulders

install  the external  display,  keyboard  and mouse  properly and  within comfort  able
reach

if you view your monitor more than your documents, place the display at the center
of your desk to minimize neck strain

Taking  care  of your  vision

Long  viewing hours,  wearing incorrect  glasses  or contact  lenses, glare,  excessive room
lighting,  poorly focused  screens, very  small typefaces  and low-contrast  displays could  stress
your  eyes.  The following sections provide  suggestions  on  how  to  reduce eyestrain.
Eyes

Rest  your eyes  frequently.

Give  your eyes regular breaks  by looking away from the monitor and  focusing

on a distant point.

Blink frequently  to  keep your  eyes from  drying out.

Display

Keep  your  display  clean.

Keep your head at a higher level than the top edge of the display so your eyes point
downward when looking at the middle of the display.

Adjust the display brightness and/or contrast to a comfortable level for enhanced text
readability  and graphics  clarity.

Eliminate glare and  reflections by:

placing your display in such a way that the side faces the window or any light
source

minimizing  room light by using drapes, shades or blinds

using a task light

changing the display viewing  angle

using a glare-reduction filter

using a  display visor,  such as  a  piece  of  cardboard extended  from the  display top
front edge

Avoid adjusting your  display to an awkward  viewing angle.

Avoid looking  at  bright  light  sources, such as open windows,  for extended periods
of time.

Developing  good  work  habits

Develop  the following work habits to make your computer use more relaxing and  productive:

Take  short breaks  regularly  and  often.

Perform  some stretching  exercises.

Breathe  fresh  air as  often as possible.

Exercise  regularly  and maintain  a  healthy  body.

-----------------------------------------------------------------------------------------------------

Warning! We do not recommend using the product on a couch or bed. If this is
unavoidable,  work  for  only short  periods,  take  breaks regularly,  and  do  some
stretching  exercises.
