Abstract

Aims: Work proper lighting means a safe, healthy and comfort conditions for
work under a lighting system that includes qualitative and quantitative
features. This study aimed to evaluate the surface local lighting of works and
eye fatigue among research and development staffs of an automotive industry.
Instrument & Methods: In this descriptive study in Research and
Development Department of an automotive industry in 2015, 126 official staffs
were selected randomly. A demographic questionnaire and the Visual Fatigue
Questionnaire (Persian Version) were used for data gathering. Hagner EC1 Luxmeter
was used to measure the local lighting. Data were analyzed by SPSS 20
software, through descriptive statistics.
Findings: The lighting in 382 stations (75.8%) was improper and less than
standard. The minimum and maximum intensity of light was between 22.4lux
in station 2 (inventory department) and 581lux in station 4 (systems and
methods department). The overall intensity in more than 50% units,
except the Systems and Methods Department, were less than the
standard (300lux). 40.4% of the participants had severe eye fatigue,
28.6% had moderate visual fatigue, 28.6% had low visual fatigue and
only 2.4% had no visual fatigue. The average of visual fatigue was
3.50±1.97.
Conclusion: The workplace lighting and the eye fatigue of computer users in
the Research and Development Department of the studied automotive industry
are not in an acceptable condition.
