摘要
目的通过对戴不合适眼镜所致老年人视疲劳的探讨，提出防治措施。方法对１００例老年视疲劳患者进行验光试镜，核对原老视镜，用Ｄｕａｎｅｓ视标检查辐辏和调节近点，并检查视功能。结果１００例（２００眼）均为老视和屈光不正，原１００例老视镜中７０％球镜和７８％的柱镜有误差（≥±０５０Ｄ），光学中心距离与瞳孔距离差异有显著性（Ｐ＜００１），９２％的光学中心距离较瞳距大２ｍｍ以上，垂直方向光学中心５２％有误差。戴不合适眼镜为主因引起视疲劳占５２％。结论戴不合适眼镜是引起老年人视疲劳的主要原因之一。
Objective\ To study asthenopia of the aged caused by inappropriate glasses.
