A new study has found that the time needed for a man to fall in love at first sight is 8.2seconds. And, if it lasts just four seconds, he may not be all that impressed. But if can break the 8.2 second barrier, he could already be in love。

最新研究发现男性对女性一见钟情只需8.2 秒。如果男性的目光在女性身上只停留了四秒钟，那表示他可能对这个女性没有太大兴趣。但如果他的目光停留的时间超过了8.2 秒，那么他可能已经坠入爱河了。

However, women let their eyes linger on men for the same length of time whether they find them attractive or not。

然而，不管男性的外表是否英俊，女性的目光停留在他们身上的时间都一样长。

According to the researchers, men use eye contact to seek out fit and fertile mates but women are more wary of attracting unwanted attention because of the risks of unwanted pregnancy and single parenthood。

研究人员认为，男性通过目光接触寻找健康、生殖力强的异性，而女性由于承担着意外怀孕和单身母亲的风险，不愿引起不必要的注意。
