Why is night shift called cat-eye?

Answer 1

The term "cat-eye" for night shift is believed to stem from the way cats' eyes reflect light in low visibility, allowing them to see well in the dark. This metaphor highlights the alertness and enhanced vision required for workers on the night shift, who must navigate and perform tasks in the absence of daylight. Additionally, the name may evoke the idea of being vigilant and aware, similar to the instinctual nature of nocturnal animals.
