目的 :了解视力正常大学生眼的调节状态 ,探讨近视眼发病的各种影响因素。方法 :应用标准对数视力表对 31名视力正常大学新生进行远、近视力及相对调节力正、负贮备的测定。结果 :视力正常大学新生远视力平均值为 1.14± 0 .13;眼相对调节力正贮备平均值为 (- 4.35± 1.87) D,负贮备平均值为 (+ 2 .74± 0 .6 2 ) D,相对调节力为 (7.10± 1.92 ) D。结论 :视力正常大学生眼的相对调节力正常。
Objective: To understand the regulation of ocular condition in normal students and to explore the various influencing factors of myopia. Methods: The standard logarithmic visual acuity chart was used to measure the positive and negative reserve of far and near vision and relative accommodation of 31 freshmen with normal vision. Results: The average visual acuity of freshmen with normal vision was 1.14 ± 0.13; the average relative positive adjusting power of eyes was (- 4.35 ± 1.87) D, the negative negative mean was (+2.74 ± 0.62) D, the relative accommodation power is (7.10 ± 1.92) D. Conclusion: The relative accommodation power of eyes of normal students is normal.
