shut and open the eyes quickly
I blinked in astonishment
he blinked his eyes nervously
she blinked away her tears
(of a light) flash on and off in a regular or intermittent way
the car's right-hand indicator was blinking
an act of shutting and opening the eyes very quickly
he was observing her every blink
a momentary gleam of light
out on the marshes there was a blink of light
