IMPACTS OF VISUAL CHANGES ON THE QUALITY OF TEACHING AND THEIR INFLUENCE ON STUDENTS’ PERFORMANCE

Abstract

The study analyzed the impacts of electronic device usage on the ocular health and academic performance of high school students. Using a qualitative approach, data were collected in classes of a full-time school through structured questionnaires. The aim was to identify visual issues such as myopia, hyperopia, and astigmatism, and to understand how environmental factors, such as lighting and exposure time, influence ocular health and learning. The results revealed that prolonged use of electronic devices, combined with inadequate lighting conditions in study environments, contributes to an increase in visual problems. Symptoms such as eye strain, blurred vision, and headaches were common among students, impairing their concentration and academic performance. The lack of regular breaks during screen use exacerbates these issues, highlighting the need for awareness of healthy study practices. Based on these findings, the study underscores the importance of interventions that promote proper technology use and improvements in the school environment. Strategies such as lighting adjustments, scheduled breaks, and adapted teaching materials are essential to prevent visual problems and ensure inclusive learning. Additionally, the personalization of pedagogical approaches can address the needs of students with visual impairments, promoting equity in education. This work reinforces the relevance of educational policies aimed at ocular health and inclusion, contributing to the well-being and academic success of students.
