          Abstract

          RESUMEN. Objetivo: Determinar la frecuencia de factores ocupacionales asociados a astenopía en trabajadores usuarios de pantallas de visualización de datos (PVD) de empresas del rubro construcción de Huaraz, 2019. Material y Métodos: Investigación observacional, transversal, de enfoque cuantitativo. Se encuestaron 234 trabajadores usuarios de PVD con 6 a más meses en el puesto laboral actual y más de 4 horas diarias frente a la PVD. El Cuestionario de Síndrome Visual Informático (CVS-Q) permitió identificar astenopía. La prueba Chi cuadrado de independencia, la prueba U Mann Whitney y razón de prevalencias permitieron identificar los factores asociados a astenopía. Se utilizó el paquete estadístico SPSS versión 25. Resultados: La edad promedio fue 35.8 años, el 73.08% fueron varones, el 77.78% utilizaba silla ergonómica, el 60.68% toma descansos breves, el 35.47% y 86.75% trabaja con iluminación y distancia a la PVD adecuada, respectivamente, y el 14.53% presentó astenopía. El puesto laboral administrativo (p<0.001), la toma de descansos breves (p=0.023), el nivel inadecuado de iluminación del ambiente laboral (p<0.001), la distancia inadecuada frente a la PVD (p<0.001), el extenso tiempo laboral en el área actual (p<0.001), la elevada cantidad de horas diarias frente a la PVD (p<0.001), la edad (p<0.001), el sexo femenino (p=0.001) y la miopía (p=0.011) fueron factores asociados a astenopía. Conclusión: Los trabajadores administrativos, de sexo femenino, de mayor edad, con mayor tiempo laboral y de horas al día frente a la PVD, que laboran con inadecuada iluminación y distancia frente a la PVD y que tienen miopía presentan mayor probabilidad de padecer astenopía.

          ABSTRACT Objective: To determine the freequency of occupational faactors assoociated with asthenopia in users of data display screens (DDS) of companies in the construction sector of Huaraz, 2019 Material and Methods: Observational, cross-sectional, quantitative approach research. 234 DDS user workers were surveyed with 6 or more months in the current job position and more than 4 hours a day in front of the DDS. The Visual Computer Syndrome Questionnaire (CVS-Q) allowed to identify asthenopia. Chi Squaare Test, U Mann Whitney and prevalence ratio allowed us to identify the factors associated with asthenopia. The statistical package SPSS version 25, was used. Results: The average age was 35.8 years, 73.08% were male, 77.78% used ergonomic chair, 60.68% take short breaks, 35.47% and 86.75% worked with adequate lighting and distance to the PVD, respectively, and 14.53% presented asthenopia. The administrative job position (p <0.001), the taking of short breaks (p=0.023), the inadequate level of illumination of the work environment (p <0.001), the inadequate distance in front of the DDS (p <0.001), the extensive working time in the current area (p <0.001), the high number of daily hours in front of the DDS (p <0.001), age (p <0.001), feemale seex (p = 0.001) and myopia (p = 0.011) weere factors assoociated wiith asthenopia. Conclusion: Administrative workers, female, older, with longer working time and hours a day in front of the PVD, who work with inadequate lighting and distance in front of the PVD and have myopia are more likely to suffer asthenopia.

          Digital eye strain: prevalence, measurement and amelioration

          Digital device usage has increased substantially in recent years across all age groups, so that extensive daily use for both social and professional purposes is now normal. Digital eye strain (DES), also known as computer vision syndrome, encompasses a range of ocular and visual symptoms, and estimates suggest its prevalence may be 50% or more among computer users. Symptoms fall into two main categories: those linked to accommodative or binocular vision stress, and external symptoms linked to dry eye. Although symptoms are typically transient, they may be frequent and persistent, and have an economic impact when vocational computer users are affected. DES may be identified and measured using one of several available questionnaires, or objective evaluations of parameters such as critical flicker–fusion frequency, blink rate and completeness, accommodative function and pupil characteristics may be used to provide indices of visual fatigue. Correlations between objective and subjective measures are not always apparent. A range of management approaches exist for DES including correction of refractive error and/or presbyopia, management of dry eye, incorporating regular screen breaks and consideration of vergence and accommodative problems. Recently, several authors have explored the putative role of blue light-filtering spectacle lenses on treating DES, with mixed results. Given the high prevalence of DES and near-universal use of digital devices, it is essential that eye care practitioners are able to provide advice and management options based on quality research evidence.

            Computer Use and Vision-Related Problems Among University Students In Ajman, United Arab Emirate

            Background: The extensive use of computers as medium of teaching and learning in universities necessitates introspection into the extent of computer related health disorders among student population. Aim: This study was undertaken to assess the pattern of computer usage and related visual problems, among University students in Ajman, United Arab Emirates. Materials and Methods: A total of 500 Students studying in Gulf Medical University, Ajman and Ajman University of Science and Technology were recruited into this study. Demographic characteristics, pattern of usage of computers and associated visual symptoms were recorded in a validated self-administered questionnaire. Chi-square test was used to determine the significance of the observed differences between the variables. The level of statistical significance was at P < 0.05. The crude odds ratio (OR) was determined using simple binary logistic regression and adjusted OR was calculated using the multiple logistic regression. Results: The mean age of participants was 20.4 (3.2) years. The analysis of racial data reveals that 50% (236/471) students were from Middle East, 32% (151/471) from other parts of Asia, 11% (52/471) from Africa, 4% (19/471) from America and 3% (14/471) from Europe. The most common visual problems reported among computer users were headache - 53.3% (251/471), burning sensation in the eyes - 54.8% (258/471) and tired eyes - 48% (226/471). Female students were found to be at a higher risk. Nearly 72% of students reported frequent interruption of computer work. Headache caused interruption of work in 43.85% (110/168) of the students while tired eyes caused interruption of work in 43.5% (98/168) of the students. When the screen was viewed at distance more than 50 cm, the prevalence of headaches decreased by 38% (50-100 cm – OR: 0.62, 95% of the confidence interval [CI]: 0.42-0.92). Prevalence of tired eyes increased by 89% when screen filters were not used (OR: 1.894, 95% CI: 1.065-3.368). Conclusion: High prevalence of vision related problems was noted among university students. Sustained periods of close screen work without screen filters were found to be associated with occurrence of the symptoms and increased interruptions of work of the students. There is a need to increase the ergonomic awareness among students and corrective measures need to be implemented to reduce the impact of computer related vision problems.

              Evaluation of the Factors which Contribute to the Ocular Complaints in Computer Users.

              Use of information technology hardware given new heights to professional success rate and saves time but on the other hand its harmful effect has introduced an array of health related complaints causing hazards for our human health. Increased use of computers has led to an increase in the number of patients with ocular complaints which are being grouped together as computer vision syndrome (CVS). In view of that, this study was undertaken to find out the ocular complaints and the factors contributing to occurrence of such problems in computer users.
