Ergonomic Aspect of Eye Health

Abstract

Eye is one of five senses that provide information about the condition of the surrounding environment in the form of electromagnetic waves. Electromagnetic waves received by the eye and focused to the retina in visual system. The retina converts electromagnetic waves into nerve impulses, then the optic nerve is delivered to the center and visual associations cortex to form visualization. The eye is able to see objects quickly because it has an accommodation mechanism and eye muscles which will move according to the movement of objects. Various factors can affect the function of the eye, one of that was near work without implementation of ergonomic aspect. In clinical ergonomic there are three aspects which influence the eye health, namely task, organization and environment. Task, related to what is seen, its size, the contrast of objects with the background, and how it works. Organizational aspect related to working hours, rest hours, work shifts. Environment related to the intensity of lighting, various harmful residues to the eyes, chemical hazard, work accidents, etc. Application of ergonomics working principles such as standardized operating procedure (SOP), rest hours, the use of personal protective equipment (PPE) are important to maintain good visual function.
