EVALUACIÓN DE LOS EFECTOS SOBRE LA SALUD VISUAL Y MUSCULOESQUELETICA DE LOS TRABAJADORES QUE DESEMPEÑAN LABORES DE OFICINA EN UNA EMPRESA DISTRIBUIDORA DE EQUIPOS ELECTRÓNICOS CON EXPOSICIÓN A PANTALLAS DE VISUALIZACIÓN DE DATOS

Abstract

The typical use of data view screens and their influence on the skeletal muscle and visual workers health, whether if it´s the light exposition or the postures´ adoption in front of a computer is the cause of continuous research. The objective of this study is to determine the visual and musculoskeletal disorders due to the prolonged use of data visualization screens (PDV) in people who perform a workday. This is an observational, cross-sectional study measure of 105 workers who carry out continuous work with exposure to the screen in all the work areas of a Electronic distribution company at Guayaquil. The National Institute of Health and Work Hygiene (INSHT) check list was applied to identifies the employees that use the equipment with data visualization screens (PVD), recognizing the collaborators who fulfilled the requirements of exposure to PVD. The job positions in the different areas of the company are analyzed by identifying two types of posts which the light factor was quantified through a certified Luxometer, under the parameters established in the Technical Lighting Standard at the INSHT Post, at the same time, photos and videos were taken of the work stations that would be subjected to ROSA methods. Results were obtained that show a low luminous quality in almost all work areas, despite having contact with natural light due to the use of screens and skylights, which is attributed as a cause of reports visual disturbance in the evening, eye redness , use of therapeutic tears, the ROSA Method reveals alert values about the design of the analyzed posts. In conclusion, it could not be determined if the poor lighting is the exclusive generator of the visual symptoms, what can verified that inadequate lighting may people acquires unhealthy postures, which influences the results obtained with the ROSA method , which indicates prompt intervention in the restructuring of jobs.
