Conventional optometric wisdom holds that accommodative infacility may result in asthenopic symptoms, yet the literature contains little support for this belief. We determined whether failure to achieve 8 cycles per minute of binocular accommodative facility or 11 cycles per minute of monocular accommodative facility tends to be associated with symptoms. Sixty subjects were given questionnaires to determine whether they were symptomatic. Monocular and binocular accommodative rock using plus and minus 2 D lenses was performed. Statistical analysis indicates that symptomatic subjects performed significantly poorer than asymptomatic subjects on both monocular and binocular facility tests. Patients presenting with asthenopic symptoms should therefore be tested for accommodative infacility.
传统验光观点认为调节灵活性不足可能导致视疲劳症状，但文献中几乎没有证据支持这一观点。我们研究了双眼调节灵活性未达到每分钟8个循环或单眼调节灵活性未达到每分钟11个循环是否往往与症状相关。60名受试者填写问卷以确定他们是否有症状。使用±2D镜片进行单眼和双眼调节摆动试验。统计分析表明，在单眼和双眼调节灵活性测试中，有症状的受试者表现明显比无症状的受试者差。因此，有视疲劳症状的患者应进行调节灵活性不足的检测。
