A quantitative approachment of the present study aims to stablish the association between lighting uniformity and the exposure time to a DDS with the visual fatigue in administrative jobs. The evaluation took a representative sample of 61 out of 266 employees in a company located in Callao, whose job consisted in using a computer for more than 5 hours a day. The data collection took place between Setember and November of 2016. The results were obtained from a survey and allowed the present study to identify the presence of visual fatigue and exposure time. Besides, the study considered a measurement of lighting levels for each administrative job. The hypothesis of the present study sustain the direct connection between lighting uniformity, exposure time to a DDS and the visual fatigue in administrative jobs. Results: The statistical analysis the Pearson's Chi-square determined the association between exposure time and visual fatigue (X2 = 8.498 and p = 0.014) and the association between the uniformity of the illumination with visual fatigue is not significant (X2 = 0.607 and p = 0.436). Conclusion: In the study population it determined a significant association between the time of exposure to a Data Display Screen (DDS) and visual fatigue, given that 63.9% of workers in the sample reports visual fatigue and 90.2% working more than 5 hours a day, using a DDS during their workday. It was also determined that the association between lighting uniformity and visual fatigue is not significant, given that only 32.79% of employees reported having visual fatigue and their jobs positions do not have a uniform distribution of lighting.
