Visual Stress reportedly affects 5-12% of the general population and 20-30% of people with dyslexia. Symptoms are characterized by visual discomfort and perceptual distortions when viewing lines of text, and can be exacerbated by fluorescent lighting and bright paper. In this study, nursing students reported their levels of visual discomfort while reading text on contemporary (ultra-white) paper and on beige-coloured paper, under either standard classroom-lighting (600 lux; n = 31) or reduced illumination(400 lux; n = 25). Under the standard lighting, 10(28%) of subjects reported notable levels of Visual Stress (scoring ≥15 on a visual discomfort scale of 1-30). When reading from the beige-coloured paper the group reported less discomfort across all six symptoms. These differences were statistically significant for five of the six symptoms and the total discomfort score. The results were similar but less pronounced for the group in the reduced illumination condition. This study found that Visual Stress-related reading discomfort can also affect capable readers and, moreover, that simple adjustments to lighting and/or visual media can alleviate such symptoms. The implications of these findings for organisational practice in education and healthcare settings are discussed.  El estres visual puede afectar del 5 al 12% de la poblacion general y del 20 al 30% de las personas con dislexia. Los sintomas se caracterizan por incomodidad visual y distorsiones de la percepcion visual en la lectura, y pueden agravarse con la iluminacion fluorescente y el papel brillante. En este estudio, estudiantes de enfermeria expresan niveles de incomodidad visual al leer texto en papel ultrablanco y en papel de color beige, ya sea con iluminacion estandar del aula (600 lux; n = 31) o con iluminacion reducida (400 lux ; n = 25). Bajo la iluminacion estandar, 10 (28%) de los sujetos informaron niveles notables de estres visual (puntuacion ? 15 en una escala de1 a 30). Al leer en color beige, el grupo presento menos malestar en los sintomas. Estas diferencias fueron estadisticamente significativas para cinco sintomas y el total de malestar. Los resultados fueron menos pronunciados para el grupo en la condicion de iluminacion reducida. Encontrandose que la incomodidad de lectura relacionada con estres visual tambien puede afectar a lectores expertos y, ademas, que simples ajustes a la iluminacion y/o medios visuales pueden reducirla. Se discuten las implicaciones para la practica en entornos educativos y sanitarios.
