摘要

蓝光通常会引起不适眩光,但尚不清楚哪些视觉色素是主要因素。因此,我们进行了一项实验,通过应用无声替代方法在中央凹和外周视觉中保持L和M视锥的刺激完整,阐明了两种视觉色素,即S视锥和表达黑色素的本质光敏视网膜神经节细胞(ipRGCs)的影响。刺激物的色温分别为2700 K和8000 K,亮度值为1000 cd/m2。将背景亮度设置为5.0cd/m 2以产生感光条件。参与者依次暴露在两种刺激的不适眩光下,并使用成对比较进行评估。结果表明,ipRGCs的刺激显著增加了周围视觉的不适眩光,而S锥的刺激则没有,这表明ipRGCs在蓝光引起的不适强光的发生中起着至关重要的作用。

Contribution of Melanopsin to Discomfort Glare Perception
Blue light often causes discomfort glare, but it is unclear which visual pigments are the main contributing factors. Thus, we conducted an experiment to clarify the effects of two visual pigments, S-cones and melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs), by applying a silent substitution method for keeping the stimulations of L and M cones intact in foveal and peripheral vision. The color temperatures of the stimuli were 2700 K and 8000 K, and the luminance value was 1000 cd/m 2 . The background luminance was set to 5.0 cd/m 2 to create photopic conditions. Participants were exposed to the discomfort glare of the two stimuli sequentially and evaluated them using pairwise comparisons. The results showed that stimulation of ipRGCs significantly increases the discomfort glare in peripheral vision whereas the stimulation of S-cones does not, indicating that ipRGCs play a crucial role in the occurrence of discomfort glare caused by blue light.
