Occupational Vision Assessments.


Our 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 efficiency.

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.

 

Prescription Safety Glasses

We are regional manufacturer authorised dealer for Titmus Prescription safety glasses. We carry the Full Range of Titmus Prescription Frames for your selection. We provide comprehensive eye care and can recommend users requirements for our cooperate clients.

 

Vision Screening

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 efficiency.

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.
