项目摘要

Visual Acuity : We evaluated whether we could manage to follow up the refractions of students only by the examinations of their uncorrected visions. As the results there isnot any big problem and no further management is necessary for students having the visual acuity over 1.0, including those using eye-glasses or contact lenses. However, for those having the visual acuity under 1.0, we must consider refractive error, amblyopia and some other eye diseases, and consultation to the ophthalmologist is necessary. If these further managements are done, the refractive conditions at school is not necessary. But to know the refractive conditions of students, we believe that refraction examination in certain sample is necessary.Color Vision : (1) In case that test field was widened, in most of dichromats and trichromats narrowing of equation range of the snomaloscope was observed. (2) We evaluated color confusion that was seen in color vision deficiencies with industrial resistors. Regardless of type and degree of color vision defect, misidentifying of resistors were generally coincided. (3) We recommend that pseudoisochromatic plates, Panel D-15 nad Lantern Test should be employed together. Binocular Vision : In order to perform a mass-screening test, we have succeeded to examine stereoacuity in group of approximately 15 to 20 students at one time by checking the distant stereoacuity by projecting stereoscopic figures on screen in the classroom. Furthermore, it is significant to check compensatory headposture anomalies, which often occur in order to maintain good steropsis in the presence of ocular deviation.

视力：我们评估是否可以通过检查学生的未矫正视力来跟踪学生的屈光情况。结果表明，视力超过1.0的学生，包括戴眼镜或隐形眼镜的学生，没有什么大问题，也不需要进一步的管理。但是，对于视力低于1.0的人，我们必须考虑屈光不正，弱视和其他眼科疾病，并咨询眼科医生是必要的。如果做了这些进一步的管理，屈光条件在学校是没有必要的。色觉：（1）在扩大视野的情况下，大部分二色视者和三色视者的色觉方程范围变窄。(2)我们评估了在色觉缺陷中看到的工业电阻器的颜色混淆。无论色觉缺陷的类型和程度如何，电阻器的错误识别通常是一致的。(3)我们建议同时使用假等色干版、D-15版和灯笼试验。双眼视觉：为了进行大规模筛选测试，我们已经成功地检查了立体视锐度在一组约15至20名学生在同一时间通过检查远立体视锐度投影在屏幕上的立体图形在教室里。此外，检查代偿性头位异常是很重要的，这种异常经常发生，以便在存在眼偏斜的情况下保持良好的立体感。
