How to make move trigger?

Hello! Recently I made eyelashes which are a part of pupil range. So when the puppet blinks they still look stucked. I wanted to make a trigger, but I don't know is there a way to make not key, but face trigger. Current work looks like this:

Is there a way to make eyelashes disappear while puppet blinks? I managed to do this using the key system, but I need to make it so that the appearing or disappearing of eyelashes depends directly on the puppet's blinking.
