Snellen Vision Screening
Ensure Employees Meet Vision Requirements for Safe Job Performance
A Snellen vision screening evaluates basic visual acuity using a standardized eye chart. This quick and reliable test helps determine whether employees can safely perform tasks that require clear, accurate vision—supporting both safety and regulatory compliance.
What Is a Snellen Vision Screening?
A Snellen vision screening measures how clearly an employee can see at various distances. Using the familiar letter chart, the test identifies potential vision issues that may affect job performance, equipment operation, driving, or safety-sensitive tasks.
These screenings are commonly included in medical surveillance programs and respirator medical evaluations, helping employers ensure workers meet essential visual requirements.
Who Needs This Test?
Snellen vision screenings are recommended for employees who:
Operate vehicles, machinery, or heavy equipment
Perform quality control or detail-oriented inspections
Work in safety-sensitive environments
Participate in respirator medical evaluations
Require routine medical surveillance
Industries include manufacturing, warehousing, construction, transportation, healthcare, and laboratory environments.
How It Works
Vision screening is simple, fast, and requires minimal equipment:
The employee stands at a standardized distance from the Snellen chart.
They read lines of letters that become progressively smaller.
Results indicate visual clarity and whether corrective lenses may be needed.
Findings help determine if an employee meets vision requirements for specific job tasks.
Testing is available on-site at your workplace or at our OccuMed facility.
Applicable Standards:
While not tied to a single OSHA standard, Snellen vision screenings support compliance and safety requirements for:
Medical surveillance programs
Respirator medical evaluations
Job roles where accurate vision is essential (equipment operation, driving, inspection tasks)
