与人对视时那股说不清的强度——像是冒犯，又像是暴露；那双瞳孔亮着，深不见底，又不透光。 The ambiguous intensity of looking someone in the eye — at once invasive and vulnerable.

词源etymology
把 myopia（近视）、presbyopia（老花）一类词的眼科词尾 -opia（希腊语 ōps，眼）单拎出来， 让它独立成词——一整类「看」的词尾，成了「看」本身。
The ophthalmic suffix -opia (Greek ōps, eye) — of myopia, presbyopia and their kind — set loose as a word of its own: the tail-end of a whole family of “seeing” words, promoted to the seeing itself.
背景the story
《晦涩悲伤词典》原帖发布于 2012 年 12 月。定义本身（见下方引文）就值得抄一遍： 门上的孔洞，里面站着人，你却分不清自己在往里看还是往外看。
眼神接触是人类最短的距离，这个词给那三秒钟起了名。词典未收。
The Dictionary of Obscure Sorrows post ran in December 2012. The definition itself (quoted below) deserves copying out: a hole in a door, someone standing there, and you unable to tell whether you are looking in or looking out.
Eye contact is the shortest distance between people; this word names those three seconds. Not in any dictionary.

中文把动作说得很全：「对视」「四目相对」，网络上还有「眼神拉扯」。 可这些都站在动作那一侧；opia 是给那股强度起的名—— 「他看了我一眼」和「被他看了一眼」之间隔着的东西。
Chinese covers the action thoroughly — 对视, 四目相对, and the internet’s 眼神拉扯. But they all stand on the action’s side; opia names the voltage — the thing that sits between “he glanced at me” and “I was seen.”
The ambiguous intensity of looking someone in the eye, which can feel simultaneously invasive and vulnerable — their pupils glittering, bottomless and opaque — as if you were peering through a hole in the door of a house, able to tell that there's someone standing there, but unable to tell if you're looking in or looking out.与人对视时那股暧昧的强度——既像冒犯，又像暴露；那双瞳孔闪着光，深不见底又不透光——仿佛你正从一扇门上的孔洞往里看，看得出里面站着一个人，却分不清自己是在往里看，还是在往外看。（中译） John Koenig John Koenig · The Dictionary of Obscure Sorrows The Dictionary of Obscure Sorrows · 2012
Three stops of accidental opia with the stranger across the aisle, and both of them studied their phones for the rest of the ride. 自拟例句 our own example, not a quotation Video calls ruined opia; everyone is forever looking just past everyone else. 自拟例句 our own example, not a quotation 不在词典中。 非正式与创意写作；写人物第一次见面的段落，它是现成的手术刀。
