Morphology

by + an + eyelash

The meaning is directly derivable from the parts: 'by' marks the margin or amount and 'an eyelash' evokes a very small physical distance, so together they naturally mean 'by a very small margin.' This tiny-distance metaphor is cross-linguistically common (e.g. 'by a hair') and would be understandable to a B1 learner who knows the constituent words.

Etymology

The idiom by an eyelash comes from the image of an eyelash as a very tiny distance, like a race decided by the smallest gap between two runners. That's why it means 'by a very small margin'.
