VDT Lighting Recommendations

The following are general recommendations to control computer vision syndrome in the workplace.

  • User's should have regular eye examinations and discuss with the ophthalmologist or optometrist the amount of VDT use during the workday, the nature of the task being performed and current viewing distance. A co-worker can assist in measuring this distance, if a human factors specialist is not available.
  • Use appropriate viewing distance and viewing angle.
  • Use indirect instead of direct lighting, if possible.
  • Provide supplementary task lighting that is individually adjustable both in light level and position.
  • Do not place VDT's in front of windows, position perpendicular to windows.
  • Draw blinds/drapes.
  • Periodically look away from the computer screen and focus on distant objects or close the eyes for a brief period (every 20 to 30 minutes).
  • Reduce the amount of ambient lighting by dimmer switches, turning off some lights, or disconnecting one or more fluorescent bulbs.
  • Do not locate VDTs under or in front of overhead light fixtures.
  • If all else fails, use a high quality glare screen that has been approved by the American Optometric Association (AOA).
