Morphology

in + the + blink + of + an + eye

The meaning 'extremely quickly' is directly inferable from the constituents: a 'blink' of the 'eye' denotes a very brief interval, and the prepositional framing indicates occurrence within that brief time. This is a transparent, image-based metaphor with close cross-linguistic parallels (e.g. Spanish, French) so a B1 learner who knows the words will readily grasp the meaning.

Etymology

The idiom in the blink of an eye comes from the very quick closing and opening of the eye in a single blink. That's why it means 'in an instant'.
