Accommodation Disturvance on VDT Works

本研究以会津大学计算机夏令营的一名初中生为研究对象，以物体的折射变化为主要内容，对教室的延续性活动进行了调查。因此，我能够假设一件事，即早发性和晚发性近视的进展有一种差异。最后在2001年3月的亚太眼科学会现状报告中，Kajita分析了VDT作业中的调节性微波动，并检查了这些现象在距离上的减少，即所谓的调节静止状态。我让我们假设，如果做了让眼镜适合让工作距离对应眼镜的涂层，我们就可以防止来自VDT工作或度数的视疲劳，也可以作为有害射线的去除。我证明了这是有用的筛选视疲劳和掌握的条件，通过应用这一事实在诊断/治疗视疲劳。我于1998年以从事VDT工作的高校教职工为对象，试用了一套渐进式屈光透镜（远、近、中、近），用于中老年人群的VDT工作。我们比较了控制组和VDT组在测量识别开始在计算机屏幕顶部描述的汉字的时间方面的差异。结果，对照组澄清所需的调节时间为0.6-0.8秒，但根据个人工作环境显示出延长。因此，这种技术是有用的筛选，并提供了有用的信息，在矫正眼镜的选择进行了估计。

We examined a junior high school students of "Aizu university computor-summer camp" which came as continuation enterprise of a classroom mainly on refractive changes to an object. As a result, I was able to suppose a thing with the tendency that a difference was recognized by progress of myopia in time of namely early-onset and late-onset. I did on Asia pacific Academy of Ophthalmology present situation report in March, 2001 finally.Kajita analyzed for accommodative microfluctuation with VDT work, and checked that these phenomenon reduced it in the distance, socalled resting state of accommodation. I let us suppose that we could prevent from to asthenopia to come from VDT work or degree if did the coating that this thing let glasses for the appropriate work that let work distance correspond glasses and also served as the removal of harmful rays. And I proved that it was useful for screening of asthenopia and grasp of condition by applying this fact in a diagnosis/medical treatment of asthenopia. I tried a chase of visual functions as an object the university staff who engaged in, VDT work a set of progressive refractive lens (far and near, intermediate and near) with a purpose to do VDT work in the advanced aged groupes in 1998. And reduction of complains is attempted by lending these lenses to VDT worker appealing for asthenopia.We compared control and VDT groups in measuring time recognizing the character, kanji, which began to be described in computer screen top, employed Visual-Basic As a result, accommodation time necessary to clarify was 0.6-0.8 second in control group, but showed extension according to personal work environment. Consequently, this technique was useful for screening, and that information to be useful in a selection of correction glasses was provided was estimated.
