RESUMEN:
El estrés visual puede afectar del 5 al 12% de la población general y del 20 al 30% de las personas con dislexia. Los síntomas se caracterizan por incomodidad visual y distorsiones de la percepción visual en la lectura, y pueden agravarse con la iluminación fluorescente y el papel brillante. En este estudio, estudiantes de enfermería expresan niveles de incomodidad visual al leer texto en papel ultrablanco y en papel de color beige, ya sea con iluminación estándar del aula (600 lux; n = 31) o con iluminación reducida (400 lux ; n = 25). Bajo la iluminación estándar, 10 (28%) de los sujetos informaron niveles notables de estrés visual (puntuación ≥ 15 en una escala de1 a 30). Al leer en color beige, el grupo presentó menos malestar en los síntomas. Estas diferencias fueron estadísticamente significativas para cinco síntomas y el total de malestar. Los resultados fueron menos pronunciados para el grupo en la condición de iluminación reducida. Encontrándose que la incomodidad de lectura relacionada con estrés visual también puede afectar a lectores expertos y, además, que simples ajustes a la iluminación y/o medios visuales pueden reducirla. Se discuten las implicaciones para la práctica en entornos educativos y sanitarios.
