Can Science Explain Why We Kiss With Our Eyes Closed?

科学能解释我们为什么闭着眼睛亲吻吗？

Rick and Ilsa in "Casablanca." Wills and Kate on their wedding day. The "Kissing Sailor" in Times Square on V-J Day. Iconic kisses all around. Now imagine all of those beautiful people locking lips with their eyes wide open. Intensely creepy mental images, right?

《卡萨布兰卡》里的里克和伊尔莎的亲吻；威廉王子和凯特王妃在婚礼当天的深情一吻。 抗日战争胜利日，时代广场上的"亲吻水手"，还有身边各种标志性的亲吻。 现在想象一下，那些美丽的人们张大眼睛，紧紧地拥吻在一起。 真是令人毛骨悚然的画面，对吧？

There's a reason the thought of kissing with your eyes peeled immediately makes you cringe (aside from the disturbingly close view of another human's facial features). Or at least there's a possible reason, rooted in a 2016 study from Holloway University of London.

有一个原因是睁着眼睛接吻会让人感觉畏缩（观察一个人面部特征的近距离视图会有种不安的感觉）。2016年伦敦霍洛威大学的一项研究显示或者还有其他的原因。

When the paper was published in the Journal of Experimental Psychology: Human Perception and Performance, media outlets quickly extrapolated the results to the world of make-outs (because, sure, why not). Some science writers were quick to point out that the original study made no mention of kissing, but see for yourself if the findings make sense in the context of swapping spit.
