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.
