“…This finding by Untimanon [6] is supported by Fischer [7] who documented that there is no specific level of illumination which could satisfy everyone, though, generally, the optimum level of illumination is approximately 2000 lux. Thus, this study concluded that different individual has different comfort level or opinions with regards to sufficient lighting in their workplace.…”

“…The study emphasized that by increasing the lighting illumination and also by introducing short rest interval to avoid visual fatigue with increasing visual loading; visual issues reduce from 48.3% to 24.5% (reduction of 23.8%) [6]. Nevertheless, it was still reported that 20 out of 290 operators would still feel uncomfortable with increment in illumination [6].…”

Abstract. Based on the Market Watch 2012 with regards to the ASEAN region, Malaysia is the third biggest automotive manufacturing nation which employs more than 300,000 people. To accomplish their operation demands, manufacturing companies such as Proton and Perodua would utilize artificial lighting in their respective manufacturing plants. Research on the effects of artificial lighting on human expended about millions of dollars every years. Sufficient lighting is required for effective tasks completion while providing adequate visual capability, thus will ensure the safety of the operators. Eye strain, migraine and headache are among the common symptoms caused by poor lighting at workplace. This study aims to review on prior research regarding sufficient lighting while giving a special focus on light assessment techniques and tools in determining the luminous level in manufacturing plants. This study will contribute to create awareness among the manufacturing plant on the importance of lighting in term of work performance and occupational safety and health.

“…Table 3.9 presents some of the hazards involved in these occupational activities. (Dorevitch & Babin, 2001) • Musculoskeletal injury due to poor ergonomic design, handling heavy loads, repetitive muscle strain, vibrations (Martinelli & Carri, 1996) • Stressful working conditions -strenuous work pace in production lines (Bjorksten et al, 1996;Roquelaure et al, 2002) • Visual fatigue (Untimanon et al, 2006) • Exposure to chemical agents (e.g., metals & solvents in electronic circuits manufacture, drug by-products in the pharmaceutical industry) (Clapp, 2006;LaDou, 2006) • Stressful working conditions in production lines…”

Background:The process of jewellery making involves the goldsmiths working with tiny visual tasks at closer working distances, which demands high visual ability.Aim:To establish vision standards for Goldsmiths.Materials and Methods:Visual task analysis was carried out in different Goldsmith workstations. The minimal visual demands of the jobs were determined based on Grundy's nomogram. Depending on the importance of certain visual functions to perform the job, criteria for visual competency was laid down. Visual abilities of goldsmiths were evaluated in order to determine their visual capability status, based on the previously laid criteria. Job competency status of goldsmiths was determined based on the supervisors’ grading with respect to the quality and quantity of work. Visual competency and job competency of goldsmiths were then compared in order to establish vision standards.Results:Visual task analysis was carried out in 91 workstations. The median of working distance, work area, critical size of the task, and illuminance were 23 cm (IQR: 20- 29), 514.5 Sq Cm (IQR: 183-746.5), and 536.5 lux (IQR: 170-536.5), respectively. Visual abilities of 113 goldsmiths were evaluated. 44.7% of goldsmiths were found to be visually competent. Job competency status of 30 goldsmiths was obtained, in which 18 (60%) were found to be highly job competent. Based on the visual demands, vision standard for jewellery makers was developed.Conclusion:The vision standards so obtained could be used as minimum visual requirements for the entry level Goldsmiths.
