Health hazard evaluation report: HETA-2011-0149-3165, assessment of visual and neurologic effects among video hub employees - New York.
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, HETA 2011-0149-3165, 2012 Sep; :1-15
In September 2011, NIOSH received a union request for an health hazard evaluation (HHE) concerning visual and neurological symptoms among employees at a video hub office (VHO) in New York. Employees thought their symptoms may have been associated with long-term monitoring of multiple standard and high definition fiberoptic fed TV displays for audio and video imperfections. NIOSH conducted a site visit on February 2-3, 2012. We interviewed employees in a private setting to discuss their health and workplace concerns and reviewed medical records. The distances between video monitors and employee workstations were measured. During our interviews, 10 of 12 employees reported one or more health symptoms; most reported eyestrain, headache, pain or body aches, and drowsiness. A history of migraine headaches that occur more frequently at work was reported by 3 of 12 employees. We found the distance from the first row of desktop monitor workstations to the wall monitors was approximately 84 inches. The average distance from the user to the desktop monitor was 37 inches. As a result, looking back and forth between nearby and far objects that are different distances may cause eyestrain. We provided recommendations to managers and employees to help lessen eye strain and ergonomic complaints while at work.
