shades, drapes, or blinds so that glare on the screen is minimal, while
still allowing comfortable viewing of the materials around you. You
should use several lighting sources to accommodate different tasks, such
as overhead lighting for viewing your AlphaSmart 3000 and the overall
workstation area, and more focused lighting for closer desktop tasks.
Vision Care
Vision care is important, particularly if you are working for extended
periods of time. Your eyes may become irritated and fatigued. Resting
your eyes at regular intervals and keeping your glasses, lenses, and
display clean should reduce the strain on your eyes. Also, it is advisable
to have regular eye check-ups by a vision care specialist.
Work Habits
General work habits are an important part of working in a comfortable,
relaxed, and efficient manner. Take note of your work habits and
positions during the day. Try not to work for extended periods of time
on a single task. By shifting between several tasks you change the
physical demands placed upon you. In changing tasks, adjust your
posture somewhat to avoid extended strain on certain muscles. Try to
take several breaks during the day to stretch and exercise.
Health Habits and Exercise
Your existing health conditions can affect your ability to work in a
comfortable manner. Health conditions which may make it difficult to
work and may place undue stress upon your body include: Diabetes,
excessive weight, hypertension, smoking, stress, arthritis or other
inflammatory disease, and conditions affecting hormone levels
(including pregnancy and menopause).
Each individual has a threshold level of physical stress that they can
comfortable and efficiently work under without harm. However, it is
important to keep track of your physical well-being and to avoid
exceeding your threshold. If you have any of the above mentioned
physical conditions, you should regularly and carefully keep track of
how you feel as you work.
