Contrast sensitivity and comfort levels with different types of polarised glasses under steady glare
研究了稳态眩光下不同偏光眼镜对视觉对比敏感度和主观舒适度的影响，发现眼镜虽未提升对比敏感度但提高了舒适感，提示存在主观偏差。
The influence of various polarised glasses on visual performance is crucial due to their widespread. This study measured the visual contrast sensitivity (CS) of dominant eyes by quick contrast sensitivity function (qCSF) procedure at 10 spatial frequencies and 3 noise levels under nonglare, steady glare, steady glare with night lenses, and steady glare with day&night lenses, respectively. Later, the second experiment measured the subjects' subjective feelings under these four viewing conditions. The results showed that there was no significant difference in the CS between the two conditions with polarised glasses and the steady glare. However, the subjects reported greater comfort with glasses than without them. These results suggest that there was an underlying bias when people rated the polarised glasses, and the qCSF procedure was a useful tool for evaluating visual performance.
