Diseño de directrices ante emisiones de luz no natural para cuidado en salud visual de docentes de la Unidad Educativa Guayaquil dentro de su plan de seguridad

Abstract

This research work contains ergonomic recommendations for image adjustment in digital devices, to reduce the risk of developing Computer Vision Syndrome or other eye conditions. Biological mechanisms of human vision and physical magnitudes of non-natural light emitted by graphical interfaces are described. A comparative matrix is included that determines the elements of the hazard source that have the greatest damaging impact on the structural layers of the human eye. It is considered existing recommendations given by the National Institute of Safety and Health at Work of Spain, through its technical notes on prevention, as well as data obtained by this investigation. The work was developed within the security plan of the Guayaquil Educational Unit, a secondary school in the city of Ambato in Ecuador.
