How it's used
This idiom is used to describe someone who is exceptionally perceptive or capable of noticing even the smallest details. It carries a sense of intellectual sharpness or investigative insight rather than just physical vision. While it originates from classical Chinese, it is still frequently used in modern Cantonese to compliment someone's keen judgment or to warn others that they cannot easily hide the truth.
Examples
He seems to see through everything I do as if he notices every tiny detail.

Common mistake
Learners often mistake this for a literal description of eyesight. It is a metaphorical expression for mental acuity or insight, not for someone who simply has good vision or wears strong glasses.
