without blinking an eyelid

Showing no reaction

Without blinking an eyelid means showing no visible reaction to something surprising, disturbing, or outrageous—maintaining complete composure where others might flinch or hesitate.

The image is of someone so unperturbed that even the involuntary reflex of blinking doesn't occur: She heard the asking price and agreed without blinking an eyelid.

Often shortened to without blinking.
