Why Do Men Find Women With Larger Eyes Attractive?
为什么男人喜欢大眼睛妹子？
According to several university studies, research has shown that men generally find larger eyes on women more attractive.
据多个大学研究显示，男人普遍觉得大眼妹子最具吸引力。
The perceived attractiveness of larger eyes has led to a growing trend (especially in Asia) of women using cosmetics and contact lenses with larger limbal rings in an attempt to create the illusion of larger eyes. Many have even done this permanently through cosmetic surgery.
为了增加魅力，很多女性（尤其在亚洲）会采用化妆或者带美瞳的方式，加大深色瞳孔范围，使眼睛看起来更大。甚至有些直接做了永久性整容手术。
Why do men find larger eyes attractive?
那么问题来了，为什么男人喜欢大眼妹子呢？
There seems to be two separate reasons which attempt to address the question. The first is that larger eyes (along with fuller lips, bigger breasts and smaller chins) are a sign of higher levels of estrogen. Women that have higher levels of estrogen will be more successful and have an easier time conceiving than women with lower levels. This means that women with larger eyes will be seen as a better “mate”.
似乎有两个原因。首先，大眼睛（丰满嘴唇和胸部，小下巴）是雌激素高的表现。雌激素高的女性比雌激素低的女性更易怀孕。因此，大眼妹子看起来会是不错的配偶。
The second reason is that large eyes are a neotenous feature.
其次，是因为眼睛幼态成熟的机制。
A neotenous feature is a characteristic of youth shared by babies and children that humans evolved to retain so they could attract quality mates with “protective and nurturing impulses”.
幼态成熟机制是指成年人仍保持幼儿的特征，这样容易引起配偶的“保护欲”。
Since human eyes do not grow in size during its development relative to the rest of the body, the size of the eye relative to the face decreases as we grow. This means that babies have larger eyes compared to older children and adults. As a consequence, people who have large eyes are often perceived to be younger than they really are. Since perceived youth of a mate is also a sign of fertility, men tend to prefer women with neotenous features, like large eyes.
由于人的眼睛并不会随其他身体部位一样生长发育，眼睛会随着我们长大而看起来变小。因此，婴儿的眼睛看起来总是比青少年或成人要大。看起来年轻也是好生育的特征之一，所以男人更倾向选择拥有幼态成熟特征的女性，比如说有大眼睛。
Sexual Selection
最后，性别选择有关。
It's thanks to something that happens in evolution called Fisherian runaway selection. Fisherian selection suggests that, when one sex prefers mates with certain genetic traits, then, through the process of sexual selection, the other sex will come to possess the trait in increasingly exaggerated forms.
这跟我们进化中的费舍尔氏失控理论有关。根据这个理论，如果一个性别选择与具有特殊体征的异性交配，在性别选择过程中，另一性别就会刻意拥有并夸大这种体征。
