AND VISION AS
ERGONOMIC ISSUES in the WORKPLACE
THE FOLLOWING TOPICS
ARE DISCUSSED IN A 3 to 4 HOUR PRESENTATION:
A brief overview of the role of vision in the workplace. Dr. Anshel offers
his perspective on the current and future visual needs of computer users.
Good workplace lighting allows the worker to easily and accurately see details
of a given task. He also offers a brief history of lighting followed by an
overview of types of lighting, balancing brightness levels and age factors
in the workplace today.
A simplified presentation of the anatomy and functioning of the eyeball and
visual system. A comparison of the eye to a camera is used to dispel some
common misconceptions. Visual processing in the brain is also briefly discussed.
The use of two eyes together instead of each individually is a significant
feature which separates the human visual system from others. How we use both
eyes in conjunction with our focusing system is discussed. Important ramifications
of eye position and computer use are noted. This material is designed for
the listener with a non-medical background.
HUMAN VISION: A historical perspective is developed to show how our visual
system was originally designed and used. A comparison with today's visual
demands and adaptations is discussed.
With more people working longer and more productively into their lives, the
aging factor in vision cannot be ignored. Our focusing ability changes throughout
our lifetime and becomes a significant factor after the age of 40. How we
need to change our visual habits, as well as our lighting needs after that
time and what can be done about it are some of the areas considered.
AND VISUAL DEMANDS: Our eyes are designed to be used mostly in well lighted
situations. However, with artificial light being so predominant we must make
yet another adaptation. Emphasis will be placed on lighting for overall health,
safety and comfort in the workplace. An overview of lighting requirements
for computers and how it differs from traditional office lighting is presented.
We will learn to identify risk factors, such as direct and indirect glare,
and take steps to correct potentially harmful situations.
BODY POSTURE: Reading books and papers on a desk differs greatly from
viewing a VDT screen. It places new demands on our visual system as well as
body posture. We are visually oriented; our bodies will often change to ease
the stress on our eyes. These effects will be documented and remedies offered.
INDUSTRY: Today's industrial setting is also changing rapidly. With new
technology in safety glasses and more concern for functional vision concerns
in performing industrial work, the area of eye protection takes on a whole
new dimension. These concepts will be developed and explained during this
We will present various methods for controlling lighting so that it works
for the worker. Examples of controls include blinds, louvers, partitions,
spacing, finishes and switching. Specific attention will be given VDT lighting
control. The importance of individual task lighting will be discussed, as
well as a thorough overview of lamp color, efficiency and maintenance. Visual
solutions include general eyecare, computer eyeglasses, contact lenses, terminal
position, screen reflections, body posture, working conditions, breaks and
more. Specific eye exercises are detailed to assist in the ongoing process
of relieving eye stress.
VISION TESTING: One of the most misunderstood areas of visual function
is how the eyes are processing information while viewing the computer. A new
and unique software program is now available to perform visual tests right
on the computer screen. A complete presentation will describe the program
and how to fit it into a complete ergonomic program.
An open question and answer session is scheduled to assure that participants
understand the material presented. Any aspect of lighting and vision care
can be addressed.
