项目摘要

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.

我们调查了一名来自爱足大学计算机夏令营的初中生，该夏令营是一间以物体屈光变化为主的教室的延续企业。因此，我能够假设这样一种趋势，即近视的进展在早发和晚发的时间内是不同的。我在2001年3月完成了亚太眼科学会眼科现状报告，Kajita分析了VDT工作中的调节性微波动，并检查了这些现象是否在远处减少了调节，即所谓的静息调节状态。我假设我们可以防止来自VDT工作或程度的弱视，如果这个东西做了让眼镜工作的涂层，让工作距离相应的眼镜，也起到了去除有害光线的作用。并将这一事实应用到视疲劳的诊断和治疗中，证明了这一事实对视疲劳的筛查和病情的掌握是有用的。1998年，从事VDT工作的大学工作人员以追逐视觉功能为对象，研制了一套递进屈光透镜(远近、中、近)，目的是在高龄人群中做VDT工作。我们比较了对照组和VDT组在识别汉字的时间上的差异，汉字开始在电脑屏幕上方被描述，结果是，对照组需要0.6-0.8秒的调节时间才能澄清，但根据个人的工作环境表现出延长的时间。因此，该技术对于筛选是有用的，并且估计了在选择矫正眼镜时有用的信息。
