| 摘 要： | 用标准对数视力表对36名学生进行视力测定,结果表明,在2.5 m(或7.5 m)处所测值换算为5 m视力与5 m所测视力无显著差异(a=0.005),证实了使用标准对数视力表可变距优点。将2.5 m和7.5 m所测视力与5 m视力相比较,发现被测者中有15名完全不同(占41.67%),表明标准对数视力表的小数记录有商榷之处。

| Abstract: | Carries on the vision determination through the standard logarithm visual chart to 36 students,the result of that in the 2.5 m(or 7.5 m) quarter measured the value conversion is the 5 m vision and 5 m measures the vision was not marked difference(a=0.005),Has proven used standard logarithm visual chart invariable distance merit.Compared with 2.5 m and 7.5 m measured that the 5 m vision,have 15 difference in the tests,indicated that the standard logarithm visual chart the decimal record has place of the discussion. |
