Lenovo ThinkVision E28u-20 28" 4K HDR Monitor - Manual (Page 18)

Here are some additional tips for comfortable viewing of your display ：
• Use adequate lighting for the type of work you do.
• Use display brightness, contrast, and image controls (if available) to optimize the
image on the screen for your visual needs.
• Keep the display screen clean so that you can see the content clearly.
Long periods of focused visual activity tend to strain the eyes. Be sure to periodically
move away from the display screen and gaze at a distant object to relax your eye
muscles. If you have any questions about eye strain or visual discomfort, consult
vision care professional for advice.
Tips on Healthy Work Habits
The following is a summary of some important factors that are useful to keep you
comfortable and productive while using your computer.

Good posture comes from equipment placement: The layout of your work area
and the placement of your computer equipment can have a significant impact
on your posture while using the computer. Be sure to follow the tips listed in "
Arrange Your Working Area" on pages 2-1 to optimize the placement and
orientation of your equipment so you can maintain comfortable posture and
efficiency. In addition, be sure to use the adjustment features of your computer
components and office furniture to meet your needs, and adjust them over time
as your needs change.

Slight changes in posture help keep you comfortable: the longer you sit in
front of a computer, the more important it becomes to pay attention to your
work posture. Avoid maintaining one posture for long periods. Regular slight
changes in posture can help prevent possible discomfort. Use the adjustment
function provided by office furniture or equipment to adapt to changes in
posture.

Regular short breaks help ensure healthy computing: Because computing is
primarily a static activity, it is especially important to take short breaks during
the workday. Take regular breaks to stand in front of your work area, stretch
your limbs, walk around or have a drink, or otherwise take a short break from
using the computer. Taking short breaks during work allows for changes in
body posture that can help you stay comfortable and productive while
working.
