SÁNCHEZ-BRAU, Mar; DOMÉNECH, Begoña; BROCAL, Francisco; QUESADA, José Antonio; SEGUÍ-CRESPO, Mar. Prevalence of Computer Vision Syndrome and Its Relationship with Ergonomic and Individual Factors in Presbyopic VDT Workers Using Progressive Addition Lenses.

Este estudio transversal estimó la prevalencia del síndrome de visión por computadora (CVS) y analizó su relación con la exposición del terminal de visualización de video (VDT), así como las características sociodemográficas, refractivas, ambientales y ergonómicas en 109 trabajadores de VDT presbiópicos que usan lentes de adición progresiva (PAL). Se recomienda proporcionar capacitación e información a los trabajadores sobre la importancia de una iluminación adecuada y posturas ergonómicas durante el uso de VDT para disminuir el CVS y aumentar la calidad de vida en el lugar de trabajo.
 
Aquest estudi transversal va estimar la prevalença de la síndrome de visió per computadora (CVS) i va analitzar la seua relació amb l'exposició del terminal de visualització de vídeo (VDT), així com les característiques sociodemogràfiques, refractives, ambientals i ergonòmiques en 109 treballadors de VDT presbiòpics que usen lents d'addició progressiva (PAL). Es recomana proporcionar capacitació i informació als treballadors sobre la importància d'una il·luminació adequada i postures ergonòmiques durant l'ús de VDT per a disminuir el CVS i augmentar la qualitat de vida en el lloc de treball.
 
This cross-sectional study estimated computer vision syndrome (CVS) prevalence and analysed its relationship with video display terminal (VDT) exposure, as well as sociodemographic, refractive, environmental, and ergonomic characteristics in 109 presbyopic VDT workers wearing progressive addition lenses (PALs). Usual spectacles were measured with a lens analyser, and subjective refraction was performed by an optometrist. CVS was measured with the CVS-Q©. VDT exposure was collected. Ergonomic evaluations were conducted in a normal working posture looking at the screen. Air temperature and relative humidity were measured (thermohygrometer), and illumination was measured (luxmeter). Descriptive analysis and differences in CVS prevalence, as a function of the explanatory variables, were performed (chi-square test). Multivariate logistic regression was used to identify factors associated with CVS (OR and 95% CI). The mean age was 54.0 ± 4.8 years, and 43.1% were women. The mean hours of VDT use at work was 6.5 ± 1.3 hours/day. The prevalence of CVS was 74.3%. CVS was significantly associated with women (OR 3.40; 95% CI, 1.12–10.33), non-neutral neck posture (OR 3.27; 95% CI, 1.03–10.41) and altered workplace lighting (OR 3.64; 95% CI, 1.22–10.81). Providing training and information to workers regarding the importance of adequate lighting and ergonomic postures during VDT use is advised to decrease CVS and increase workplace quality of life.
