Occupational Vision Assessments.
patients come from a wide varieties of occupations and workplace
environments. During our comprehensive eye examination, we try to
consider all aspects of the relationship between work and vision,
visual performance, eye safety and health.
Occupational history includes a complete
description of both the visual task and the health hazards within the
workplace environment. Completing an assessment of the patient's work
environment and multiple workplace tasks should enable the optometrist
to prescribe appropriate treatments to maximize the patientís visual
The usual starting point for enhancing a
patient's workplace performance is the comprehensive eye examination
resulting in treatment of any eye disease, binocular vision disorder,
or refractive problem. From this starting point, occupational vision
assessment extends beyond the common tests and treatments to those
specifically required for the workplace environment.

Within the workplace, vision screenings or
examinations are often conducted to ensure the minimum level of
functioning needed to accomplish specific visual tasks. These
procedures can be conducted upon employment (placement) and
periodically throughout a workerís career.
Initial testing should include visual acuity (at
various distances), color vision, binocular interaction, Stereo Vision
tests, refractive error, and possibly visual fields. Tonometry and
other ocular health tests may also be performed. Results from these
tests can help with proper employee placement and aid in documenting
entering visual functioning.
Visual Task Details.
We are happy to do worksites survey, during
these visits our optometrist will assess and record information
regarding each workerís tasks. The survey must include the specific
visual tasks entailed in the essential duties of each position.
For example, tasks performed by a lathe operator
may include alignment of the cutting tool with the metal or wood
stock, observation of the cutting action when the machine is engaged,
and setting instrument controls to ensure proper dimensions. Workers
need good stereo vision and ability to do close work. While a forklift
operator or a crane driver may need to move safely throughout a
warehouse with a load, to position the load accurately in three
dimensions in front of the storage position, and, finally, to move the
forklift / crane forward to place the load safely in its precise
intended location. The operator may need to read a list on a hand-held
piece of paper (from 33cm) or to read numbers or letters on crates or
boxes (from 3m to 6m) to determine what exact load is required. And to
judge distances very accurately. The ability to appreciate the depth
of one object relative to another is often required for efficient and
safe job performance
Accurate measurement of visual detail (e.g., for
the forklift operator, the sizes of letters on a box) can be made to
calculate an absolute visual acuity requirement taking into account
the maximum required viewing distance.
Also contrast plays an important element in
visibility. Low contrast objects are difficult to see, regardless of
their size. Increasing task contrast is an important means of
increasing overall performance. When visual performance is less than
optimal, even with the recommended level of illumination, auxiliary
lighting may be beneficial.
Viewing time also plays a significant role in
visual performance. The recognition of details that are more difficult
to see requires a longer viewing time. For operations in which viewing
time cannot be changed (e.g., assembly line work), color coding and
other strategies can reduce search time and improve workerís
Lighting. General and specific workstation
lighting should also be assessed especially in areas of low
productivity or low-quality workmanship, and in situations where
workers complain of difficulty seeing task detail.
Job Safety Requirements and Vision Standards
Vision standards are set for specific jobs to
ensure that workers have the necessary vision skills to accomplish
their required tasks in a safe and efficient manner..
A strict color vision standard has the most potential for eliminating
individuals from consideration for specific task assignments.
Approximately 8 percent of males and 0.4 percent of females have
inherited a color vision defect.
