检测了不同照明条件及用眼强度对 1 0 0名大学生和 50名中学生视觉感受和视力的影响。结果显示 :照度在 50 0～ 1 0 0 0 lx视觉感受最佳 ,照度在3 0 0 lx时视觉感受是可以接受的。照度下降或用眼强度增加 ,视觉疲劳程度亦增加。虽然照度在 1 0 0 lx时 ,视力接近正常 ,但维持正常视力 ,照度应大于 2 0 0 lx。提示 :长期高强度用眼或低照度条件下学习是造成学生视觉疲劳和视力下降的直接原因之一 ,故应改善用眼卫生和学习场所的照明条件 The effects of different lighting conditions and eye intensity on the visual perception and visual acuity of 100 college students and 50 middle school students were examined. The results show that: the illumination at 50 0 ~ 1 0 0 0 lx best visual experience, illumination at 300 lx visual experience is acceptable. Decreased illumination or eye intensity increases, visual fatigue also increased. Although the illumination at 100 lx, visual acuity near normal, but maintain normal vision, illumination should be greater than 200 lx. Tip: Long-term high-intensity use of eye or low light conditions is the result of visual fatigue and vision loss of students one of the direct causes, it should be to improve the use of eye health and learning lighting conditions
