This study was performed between 2004 and 2011 at mail sorting facilities in Sweden. During this time, different interventions were performed. The first was a lighting intervention that had a positive impact on the postal workers, especially those with eyestrain. A new lighting system also improved the illuminance and gave better light distribution. The second intervention involved new personal spectacles for the postal workers who needed them and this had a positive effect on eyestrain. The third intervention involved a specific type of sorting spectacles for the postal workers who already used progressive lenses privately. The reading distances that the postal workers had while sorting the mail was inverted to the distances in their regular progressive lenses. The new sorting spectacles had a positive effect on head postures and on muscular activity.
这项研究于2004年至2011年期间在瑞典的邮件分拣设施中进行。在此期间，实施了不同的干预措施。第一项是照明干预，对邮政工作人员产生了积极影响，尤其是那些有眼睛疲劳问题的工作人员。新的照明系统还提高了照度并提供了更好的光分布。第二项干预措施是为有需要的邮政工作人员提供新的个人眼镜，这对眼睛疲劳有积极影响。第三项干预措施是为那些已经私下使用渐进多焦点眼镜的邮政工作人员提供一种特定类型的分拣眼镜。邮政工作人员在分拣邮件时的阅读距离与他们常规渐进多焦点眼镜的距离相反。新的分拣眼镜对头位和肌肉活动有积极影响。
