Keywords:
Ergonomics, Eye fatigue, Electronic workersAbstract
This study was a cross-sectional descriptive study. The objective was to study the eye fatigue of 300 workers in an electronics manufacturing industry. Data were collected using the structured questionnaire of eyes’ symptom, eye fatigue was measured by Critical Flicker Fusion (CFF) test, visual acuity examination. The results of the study found that 300 electronic workers had eye fatigue (42.00%), and the highest prevalence found at the winding, appearance inspection and packing processes, respectively. Adverse symptoms of eye fatigue during working or the end of day were mostly eye pain and eye irritation. Symptoms of eye fatigue at the end of the working day were found in every work group which had the highest prevalence with neck or shoulder pain in assembly and inspection group. Visual acuity was not suitable for the job which was found in 22.3% of workers. The most common visual abnormalities were farsightedness vision (22.66%), near sightedness vision (11.33%), and phoria (3.66%). The prevalence of eye fatigue and abnormal vision obtained can be used for annual health monitoring and health surveillance of electronic workers.
