4.7. Ergonomics
PLEASE NOTE!
Avoid dazzle, reflections and a light-dark contrast that
is too strong in order to protect your eyes.
The notebook should never be placed next to a window because
this is the brightest part of the room in daylight. This brightness
can make it more difficult for the eyes to adjust to the darker
display. The notebook should always be positioned so that the
direction of vision is parallel to the window front.
Setting up the notebook with your back to the window is
incorrect as reflections from the bright window on the screen
will then be unavoidable. A position looking onto the window is
also incorrect as the contrast between the dark screen and the
bright daylight can cause problems for the eyes to adjust and
result in problems.
The parallel line of vision should also be maintained in relation
to artificial lighting equipment.
In other words, the same criteria and principles apply where
the workspace is illuminated with artificial light. Where space
restrictions make it impossible to set up the screen as described,
then correct positioning (rotating, tilting) of the notebook/
screen can prevent dazzling, reflections and excessive bright-
dark contrast, etc. In many cases, an improvement can also
be achieved by using slats or vertical blinds on the windows,
partition walls or by changing the artificial lighting equipment.
