Students of the Naval Academy Preparatory School (NAPS) class of 1978 to 1979 were randomly divided into three groups, one-third of the class receiving their correlation for distant vision with a no. 1 pink tint to be used for reading (the placebo group); one-third of the class receiving +1.25 D added to their distance correction with 2 delta base-in each eye, in glasses to be used for reading; and one-third of the class receiving bifocals, incorporating their distance correction with a +1.50 D near addition. The refractive error at distance for all 232 students was determined under cycloplegia. At the end of 5 months, a repeat cycloplegic refraction showed nonsignificant myopic shifts (Wilcoxon test) of -0.08 +/- 0.29 D in the placebo group, -0.07 +/- 0.25 D in the plus-with-prism group, and -0.06 +/- 0.18 D in the bifocal group. This research note is preliminary to a followup at academic graduation of these same students from the Naval Academy in 1983.
1978年至1979年海军学院预备学校（NAPS）的学生被随机分为三组，该班级三分之一的学生在阅读时使用1号粉红色镜片来矫正远视力（安慰剂组）；三分之一的学生在阅读眼镜中，每只眼睛增加 +1.25 D 的度数并伴有2棱镜底向内；三分之一的学生使用双焦点镜片，其远视力矫正度数加上 +1.50 D 的近用附加度数。在睫状肌麻痹下测定了所有232名学生的远视力屈光不正情况。5个月末，再次进行睫状肌麻痹验光显示，安慰剂组近视度数无显著变化（Wilcoxon检验），为 -0.08 +/- 0.29 D；加棱镜组为 -0.07 +/- 0.25 D；双焦点镜片组为 -0.06 +/- 0.18 D。本研究报告是对这些学生1983年从海军学院毕业时进行后续跟踪研究的初步报告。
