Ergonomics

Avoid dazzle, refl ections 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 diffi cult 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 refl ections 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 artifi cial lighting
equipment.
In other words, the same criteria and principles apply where the workspace is
illuminated with artifi cial 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, refl ections 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 artifi cial lighting equipment.
Take regular breaks when working at your notebook to prevent tenseness
and fatigue.
Sitting for a long time without changing position can be uncomfortable. Correct
posture is very important for minimising the risks of physical problems or damage.
