Here's something fun - watch Michael Caine's "Art of not blinking..."
Although I think this is an interesting take on whether to blink or not blink as an acting technique, excessive blinking is often a way the body expresses some form of stress. For an actor, the stress can be coming from what they are emotionally creating (as a character) or unable to create (personally). Closing your eyes, or blinking, repeatedly can also be like a mini escape from what is happening. When we lie, we tend to blink more than when we are focused and committed. As an acting coach I see this a lot. When an actor loses focus, the blinking intensifies.
