The purpose of this study was to clarify the non-visual effects of blue-pulsed light. We observed that the nonvisual effect pupillary constriction (miosis) occurred even during blue-pulsed light irradiation of very short pulse widths (0.5-2 us). When the product of irradiance intensity and the pulse width were equal, the condition of high irradiance and short pulse width was shown to produce marked miosis. The miosis during blue light exposure was stronger than that during simultaneous exposure to blue and green light, and the alpha attenuation coefficient of the EEG for blue light exposure was also greater than that during simultaneous exposure to blue and green light, despite the double irradiance intensity of the combination. We confirmed the subadditive response to pulsed light. Even when the photon density was same, the electroretinogram photopic negative response (PhNR) during the blue-pulsed light exposure was greater than those during the exposure to lights of other colors.

这项研究的目的是澄清蓝色脉冲光的非视觉效应。我们观察到，即使在非常短脉冲宽度（0.5-2 us）的蓝色脉冲光照射下，也会发生瞳孔收缩（瞳孔缩小）的非视觉效应。当辐照强度和脉冲宽度的乘积相等时，高辐照度和短脉冲宽度的条件会产生明显的瞳孔缩小。尽管双倍辐照强度，蓝光照射时的瞳孔缩小比同时照射蓝光和绿光时更强，并且蓝光照射脑电图的α衰减系数也比同时照射蓝光和绿光时更大。的组合。 我们证实了对脉冲光的次加性响应。即使光子密度相同，蓝色脉冲光曝光期间的视网膜电图明视负响应（PhNR）也大于其他颜色光曝光期间的视网膜电图明视负响应（PhNR）。
