Tear secretion dysfunction among women workers engaged in light-on tests in the TFT-LCD industry.

In this study, although the excess risk of tear secretion dysfunction in LCD workers in comparison with LCM workers, who had higher illumination in the work environment, did not reach statistical significance, we observed high prevalence of tear secretion dysfunction in both groups of workers, and in both groups the illumination was far under the lower limit of the range (200 to 500 Lux) generally recommended [ 15 ].
