摘要
在暗适应和在明适应(1×10^(-2)熙提)条件下,对11名正常视觉的男性受试者测定了闪光亮度、闪光时间对闪光盲恢复时间的影响。观察目标为6’视角的蓝道环缺口。结果表明:①在0.45—1.5熙提(暗适应条件)和2—36熙提(明适应条件)范围内,恢复时间与闪光亮度成线性关系。②关系曲线的斜率随闪光时间的加长而增大。③引起同样恢复时间的闪光盲,明适应时所需闪光亮度为暗适应时的3—5倍,实验结果可为防闪光盲护目镜减光倍率的确定提供参数。
Under both dark-adapted and light-adapted states (1×10<sup>-2</sup> stilb), therecovery time （RT） from flashblindness in detecting a 6’ gap of LandoltRing was measured for 11 male observers with normal vision. The resultsshow: （1） the RT increases linearly with increase of luminance from 0.45 to15 stilb under dark-adapted condition and 2 to 36 stilb under light-adaptedcondition; （2） the slope of the curve relating RT to luminance increases withincrease of exposure duration) （3） the flash luminance required to producethe same RT is about 3-5 times longer under light-adapted than that underdark-adapted condition. The experimental data may serve as a basis for the determination of thetransmission factor of the protecting glass.
