不同颜色簿本对学生屈光度影响的长期观察

目的]探讨长期使用不同颜色簿本对学生屈光度的可能影响。方法]对111名小学三年级学生和151名初二年级学生进行分组调查。小学观察组56人使用黄色簿本,对照组55人使用白色簿本;中学观察组75人使用黄色簿本,对照组76人使用白色簿本。结果]1年后小学观察组学生的近视屈光度增加-0.33D,对照组学生的近视屈光度增加-0.67D;中学观察组学生的近视屈光度增加-0.38D,对照组学生的近视屈光度增加-0.69D。结论]黄色簿本改变了视觉信息环境,使用黄色簿本的学生近视发展的速度较使用白色簿本学生缓慢。

Observation of student diopter change in students using different color paper books

Objective] To observe the relation between diopter change with long - time use of different color paper in students. Methods] 111 third -grade students and 151 middle school students were included in the study. In third -grade group ,56 using yellow - colored paper while 55 using white - colored paper. In middle school group ,75 using yellow - colored paper while 76 using white - colored paper. Results] Observation group in third - grade dioper increase - 0.33D in one year,the contrast group was increased -0.67D. Observation group in middle school increase -0.38D in one year, while the contrast group increased - 0.69D. Conclusion] Yellow - colored paper change the visual environment with the result of decreasing myopia development than the white -colored paper do.
