This study explores the perspectives of professionals working with children on the impact of digital device use in schools on health and learning. A survey was conducted among 62 experts, including doctors, psychologists, and opticians, to determine safe daily limits for time spent on digital devices for different age groups. The results suggest that during the school day the recommended maximum device usage time is 1 h for young children, 2 h for pre-adolescents, and 3 h for older students. The most common adverse effects reported by experts were difficulties concentrating, addiction-like symptoms, and headaches. Respondents emphasised the importance of limiting overall usage and content, banning smartphones during school hours, and ensuring that traditional learning materials and the use of digital tools are balanced to support learning. The study also stresses the importance of regular breaks and outdoor activities to mitigate health risks. The findings provide valuable guidance for creating healthier digital learning environments in schools.
