Incidencia de la luz azul en errores refractivos de estudiantes de 15 a 17 años de la Unidad Educativa Adolfo María Astudillo, ciudad de Babahoyo, abril - septiembre 2022.

The uncontrolled use of electronic devices for academic, work or entertainment purposes, presents a high rate of optometric consultations due to exposure to blue light, whose prolonged and direct use to the eyes causes visual problems or refractive errors that occur when the eye it does not refract (bend) light properly. The objective of this study was to determine the incidence that blue light has on refractive errors presented by students between 15 and 17 years of age at the Adolfo María Astudillo Educational Unit, city of Babahoyo. April-September 2022. Methods: A quantitative, descriptive, cross-sectional study was carried out in 92 high school students, the questionnaire and visual acuity evaluation observation sheet were applied, the descriptive analysis allowed the variables to be measured. Results: Regarding the exposure of blue light with electronic devices, 59% frequently use the cell phone for more than 5 hours a day; In relation to refractive errors, 62% presented refractive errors, predominantly hyperopia with 27% followed by myopia 23% and astigmatism 12%, the symptomatology was blurred vision 31% and headache 14%, a visual acuity SC 20/40 a 20/70 39%, more frequently in 15-year-old students 36%, predominantly female with 64%. Conclusion: Blue light is harmful to our eyes when they are exposed for more than 5 hours without any eye protection; therefore, it affects the appearance of refractive errors in the study sample.
