Relación Entre las Condiciones de Iluminación y el Nivel de Agudeza Visual en Estudiantes Universitarios

Abstract

Objective: Analyze the relationship between lighting conditions and the level of visual acuity in a group of university students at the Santo Tomas University in 2024. Method: Through a descriptive observational design of case series, variables such as lighting and visual acuity were evaluated, accommodation and tear function in a group of 12 students. Lighting levels were measured at different points in two classrooms and in the offices where the evaluations were carried out. Results: a significant variability in lighting levels between different spaces. However, although changes in visual acuity associated with variations in lighting were observed, these were not statistically significant. Discussion: The analysis of clinical variables revealed a high prevalence of accommodation insufficiency and difficulty, as well as tear dysfunction in the participants, which could significantly influence visual acuity and not be directly related to lighting conditions. Conclusions: It is necessary to carry out larger, controlled studies to establish a causal relationship between lighting and visual acuity. It is recommended to improve lighting conditions in study spaces to prevent visual symptoms such as fatigue and reduce the likelihood of developing long-term eye problems.
