Impact of educational intervention on knowledge regarding ocular exercises for computer vision syndrome

The increasing use of digital devices has led to a rise in computer vision syndrome (CVS), especially among adolescents. Prolonged screen exposure results in symptoms like eye strain, dryness, irritation and headaches, affecting students' health and academic performance. Therefore, it is of interest to evaluate the effectiveness of video-assisted teaching programs in enhancing knowledge about ocular exercises for computer vision syndrome prevention. A pre-experimental, one-group pre-test post-test research design was employed, involving 60 adolescents aged 13-18 years from selected schools in Visnagar. Participants were assessed using a structured knowledge questionnaire before and after exposure to video-assisted teaching programs. Data showed a significant increase in knowledge post-intervention (p < 0.001). The percentage of participants with adequate knowledge increased from 0% to 86.66%, while those with inadequate knowledge decreased from 70% to 0%.
