Eye-CEE System for Computer Users®
is the problem?
The single most
common health problem reported by people working at a video display terminal
(VDT) is "eyestrain". Symptoms typically reported include blurred
vision or difficulty focusing, double vision, burning, sore or itchy eyes and
compensation costs have skyrocketed in recent years due to the health effects
of working on computer. In 1998, work related concerns relating to ergonomics
amounted to over 26 billion dollars! And, although musculoskeletal problems
have decreased over the past 6 years, vision concerns for computer users continues
As of now it is
the employees responsibility to ensure that they have regular eye tests carried
out by an Optometrist or Ophthalmologist. The cost of providing the eye tests,
and any glasses that may be required for VDT work, will have to be met by the
employee. However, the Occupational Safety and Health Administration (OSHA)
is considering regulations to require employers to be responsible for their
employees who use VDTs regularly on the job. Future regulations may make provision
for vision screening to be provided as a means of identifying individuals with
defective vision who need a complete eye examination.
Eye-CEE System for
The Eye-CEE (Computer
Ergonomic Evaluation) System for Computer Users is the product of several years
research and development at the Department of Optometry and Visual Science at
City University in London, England. The system meets the requirements for screening
of video display screen users in a simple, appropriate and cost effective way.
The package consists
of a computer program that may be used on any PC capable of running Microsoft
Windows. It is also network compatible. The program carries out a comprehensive
on-screen assessment of a users visual performance. The advantage of using the
display screen to present the tests, is that the results obtained provide direct
information about how the yes are performing under normal VDT viewing condition.
Conventional vision screeners which use optical systems to present the test
targets, cannot provide such direct information.
In addition to
the vision test, the program includes a detailed on-line questionnaire to establish
how the display is used and the nature of any problems the user may be experiencing
with their eyes, back, neck, arms, wrists, etc. The questionnaire also covers
problems with the display, lighting and the general layout of the workstation.
The program then performs an analysis of the responses to the questionnaire
and the results of the vision screening and provides detailed advice about the
likely causes of any problems reported and what action should be taken to resolve
The package therefore
provides a powerful too for those responsible for implementing health and safety
programs. The program is easy to use (even by non-Windows users), with detailed
on-screen instructions provided throughout. A complete assessment using the
system usually takes between 10-15 minutes.
The user is asked
a series of questions about how they use a display screen and any problems they
may have with their eyes, the display screen, lighting condition, etc. The questionnaire
is "intelligent" in as much as the questions posed are to some extent
determined by the responses given to previous questions.
Some of the vision
screening tests are based on standard tests which would be used by an Optometrist
during an eye examination, while others have been developed specifically for
the program. All the tests have been carefully designed at City University in
London and validated by the Association of Optometrists. The tests include Visual
Acuity, Letter Search, Number Search, Muscle Balance, Eye Co-ordination, Visual
Fields, a Subjective Screen Rating, and more.
The program provides
on-screen results and recommendations for the user. the recommendations are
based on the results of the questionnaire and the screening tests. The user
may print their results and recommendations to keep as a personal record of
the vision screening. The program will also provide a printed record for the
employer and a technical report to be take to the Optometrist if a full eye
examination is recommended as a result of the screening.
The program will
also provide detailed advice and recommendations tailored to each user. These
recommendations are wide-ranging and are designed to educate the user about
how to use their VDT safely and efficiently.
The program provides
a number of administration functions in addition to the basic screening tests
and report generation. It is recognized that different companies will wish to
implement health and safety programs in different ways. With this in mind, many
features of the program are configurable allowing the employer to tailor the
program to suit their particular needs. For example, the employer can select
which tests are carried out, which reports are printed and whether or not recommendations
on the general ergonomics of the workstation are provided.
The program can
readily save results of a screening to disk and provides various tools for managing
and reviewing stored records.
There is no conclusive
evidence that work with display screen equipment causes any permanent damage
to the eyes or eyesight. Furthermore, many eye problems experienced by VDT users
are related to poor workstation design or inappropriate work practices rather
than vision defects.
The Eye-CEE System
provides a simple and cost-effective way of identifying those users who are
likely to benefit from a full eye examination. Research has shown that the sensitivity
and the specificity of the on-screen vision tests performed by the Eye-CEE System
is much better than conventional screening techniques. In other words, the System
is very effective at identifying those users with vision defects. Therefore,
users who are not experiencing any eye problems will be reassured by the test.
Those users who are experiencing eye problems but pass the vision tests are
advised to consider the layout of their workstation and work practices, as well
as to seek a full examination.
Those users who
decide to seek a full eye examination at the outset will also benefit from the
Eye-CEE System because the program provides a detailed report which will assist
the Optometrist in their examination. A complete vision screening usually takes
less than 15 minutes and can be done on site, at the employees workstation or
at dedicated health-care stations. Implementing the Eye-CEE System therefore
causes minimal disruption to a users normal work routine.
By using the Eye-CEE
System, the employer can become pro-active in sight health care, and can regularly
test all display screen users for a relatively small cost. The Eye-CEE System
provides detailed advice about many aspects of health and safety in relation
to display screen and would lend support to health training schemes within a
company or organization.
The Eye-CEE System
provides a "state of the art" assessment of visual performance while
viewing a display screen. The tests are sensitive to small vision defects and
are wholly appropriate to a users normal working environment. The employee can
use the vision screener simply for reassurance to check on perceived deterioration.
The recommendations produced by the program can help the employee to understand
many of the problems associated with display screen work and to be more aware
of their own health and safety at work.
The Eye-CEE System
can be incorporated into the workplace in a number of different ways. First,
it can be purchased outright and installed by the health and safety coordinator.
The installation is self-explanatory and simple to use. Additionally, an Optometric
consultant can be sent to the company and install the program, instruct the
administrator on how to use the system and offer a seminar to the employees
which will enhance the value of the system.
support is available for the duration of the licensing agreement.
The Eye-CEE System
for Computer Users provides:
of the art" assessment of visual performance while viewing a display screen
and thus helps to identify those users who are most likely to benefit from a
full eye examination.
and recommendations based on the results of standardized vision tests.
A simple and cost-effective
solution for implementing part of a health and safety program.
