例句：lack of sleep, an allergic reaction, or the consumption of salty foods can also be factors that exacerbate dark circles.
睡眠不足、过敏反应或食用过咸的食物，也可能是加重黑眼圈的原因。
不过，千万不要错误地记成了black eye哦。black eye意为被人打得发青的眼圈，也有引申含义指丑事。
例句：a black eye is when there is bruising of the tissue under the skin around the eye.
眼周发青是指眼睛周围的皮肤组织有瘀伤。
如果是因年老而形成的眼袋，那么它的英文是bags under the eyes或under-eye bags，即眼下的“袋子”。
例句：bags under the eyes occur when weakened and sagging skin relaxes, forming a pouch.
当下垂的皮肤变得松弛时，就会形成袋状，这时眼袋就会出现。
