I did some further checking on eye movements because I wanted to find more on excessive blinking. I found several sites that address this.
Additional cues to look for in eyes during a lie may include:
- avoiding direct eye contact
- excessive blinking
- eyes shifting towards their upper left

That video has Ronald speaking in full sentences in response to NG questions about why the divorce. I believe it is from the same show where NG told Ron that she doesn't believe him.
If you watch the vid from around the 1:10 mark, you see Ron as he listens to her question and just before he speaks; he is looking straight into the camera. As soon as he starts speaking, he begins blinking. Ron again looks directly into the camera while NG speaks, but again blinks during his response. His eyelids flutter during the entire time he speaks, but he looks straight into the camera without blinking when he is not speaking, so it does not appear that his blinking is due to bright lights, IMO. He also does not appear to be high in this video.
