Study of computer vision syndrome in teachers of district 13D04 during teleworking activities

Abstract

Introduction. Computer Vision Syndrome (CVS) is a disorder that often affects individuals who frequently use electronic devices, causing symptoms that not only affect the visual and ocular system, but can also cause discomfort at the musculoskeletal level. During the transition from in-person to virtual education due to the COVID-19 pandemic, teachers significantly increased their time spent on teleworking and virtual teaching, leading to an increased incidence of CVS and symptoms affecting their comfort during and after work hours. Objective. The objective was to identify the symptoms of CVS in teachers and the strategies they have used to reduce them. Methodology. A qualitative methodology was employed using narrative design, consisting of in-depth interviews to explore the symptoms of CVS and the strategies used by affected teachers. Then, preventive material was designed and evaluated by the teachers in question. Results. Teachers presented symptoms related to CVS that affected their comfort during and after work hours. The symptoms included visual fatigue, headache, eye, and cervical irritation, and in some cases, psychosocial symptoms such as anxiety and stress. Teachers implemented various strategies, such as using eye lubricants, taking active breaks, and adopting optimal ergonomic positions in front of screens. The preventive material designed was positively evaluated by teachers. Conclusion. CVS is a frequent problem in teachers working in a virtual and teleworking mode. Implementation of strategies and availability of preventive material can reduce the symptoms related to CVS.
