Abstract

Prolonged use of computers and digital devices can lead to various physical and mental health problems. This study sought to assess computer and digital device ergonomics (CDDE) of designers, photographers, IT professionals, accountants and suppliers in several Bulgarian firms and to determine the visual (VS) and musculoskeletal (MS) symptoms reported by the respondents.

In the study, a survey was made, through a survey, using a Google Form. 42 participants were surveyed, within two weeks, in 3 age groups: up to 30 years, from 30 to 40 years and over 40 years. A significant proportion of employees reported various symptoms of VS and MS. The most affected parts of the body are identified: neck, arm/shoulder/wrist and waist. Special attention is paid to eye strain, and the symptomatology is most often related to visual symptoms, such as eye fatigue, eye pain, sensitivity to light, and others. The research covers significant issues related to health care and the importance of ergonomics in practice.
