The visual or eye standards should incorporate distance between the user and the monitor display. According to the Department of Energy (DOE) (2008), in the article entitled â€Å"Creating a Healthy Workstation Environment: Workstation Ergonomics Made Easy†, the optimum distance between the user’s eyes and the visual display by operators in seating position is 600 mm (Department of Energy (DOE), 2008, p. 7). Likewise, it was noted that special computer glasses that would assist in preventing eye fatigue and vision problems for long hours of monitoring visual displays shall be considered. It has been emphasized that the effectiveness of performance on undertaking monitoring of visual displays is affected by lighting. In this situation, it was stipulated that the operator does the monitoring in a dark room. According to ergonomic standards, light requirements actually vary depending on the performance of tasks. Since the operator focuses on monitoring visual displays from the computer, which already self-illuminating, less light is actually needed; but, it would help to provide focused task lighting (â€Å"a separate lamp†) (Department of Energy (DOE), 2008, p. 21) to assist in other tasks and prevent creating a totally dark
