Is it possible to induce eye blinking?
There are multiple ways to trigger eyeblinks:


Typically in scientific research an air puff is used.
Anything that touches the cornea.
Loud noises.
Bright lights.
Looming stimuli (i.e. something that is or looks like it is approaching fast).
More broadly anything that is unexpected and triggers a sense of danger.


So in short it is possible to visually trigger blinks but as far as I know not anything that would be an agreeable experience to the observer.
