摘　　要：目的　探讨视力正常青少年的屈光状态。方法　采用 1%阿托品麻痹睫状肌后检影验光 ,测定 6～ 18岁青少年 2 62 8只视力正常眼的屈光度。屈光类型按检影实际结果 ,本文以 <± 0 2 5D为正视 ,≥± 0 2 5D分别为远视类型或近视类型。结果　本组轻度远视占 91 2 1% ,≥± 3 2 5D占1 71% ;近视占 2 89% ;正视仅占 4 19%。各年龄组屈光度峰值都不在正视处 ,6～ 12岁组之间峰值有规律地向近视侧偏移。三种屈光类型比例的变化在 6～ 12岁组与年龄相关 ,12～ 18岁组变化与年龄增长的相关性无统计学意义。结论　青少年的正常屈光状态为轻度远视。几何光学的“正视眼”与生物医学角度的屈光“正常眼”是两个不同概念 。Objective To study the normal refraction status in the juvenile. Methods The refraction of 2628 eyes with normal vision in the age of 6～18 was measured by retinoscopy with 1% atropine cycloplegia. According to the actual diopter measured, the eyes with<±0 25D were classified into emmetropia and with ≥±0 25D into either hyperopia type or myopia type. Results Low hyperopia was 91 21%, ≥+3 25D was 1 71%, myopia was 2 89%, emmetroia only accounted for 4 19%. The concentrated peak value of dioptre was not emmetropia in any age group, and moved regularly with age to left side (to myopia side) in the groups aged 6～12. The change of the rate of three refraction types was closely related to age in the groups aged 6～12, but there was no statistical meaning in the groups aged 12～18. Conclusion The normal status of ocular refraction in the juvenile was low hyperopia. The 'emmetropia' in geometrical optics and 'the normal eye of refraction' in biomedicine were two different concepts, and should be differentiated.
