Here is Michal Caine talking about this: https://youtu.be/bZPLVDwEr7Y?t=184 https://youtu.be/bZPLVDwEr7Y?t=184 He tell a bunch of actors to always 'pick an eye' when in front of a camera. What Michel Cain does not say is that some actors prefer looking out of their 'handed' eye, believing it to have more impact. As a demo of 'handedness' in eyes, try this experiment: 1. Hold one finger around one foot in front of your face. Hold the other at arms length. Whilst try to look out of both eyes, ensure that the fingers are visually aligned with each other. This will be difficult, as the images from each eye will not correspond. 2. Slowly open and close one eye. Then do the same with the other. The slow blink from one eye (eye A) will not affect the correspondence of the fingers, whilst the slow blink from the other (eye B) will. The reason is that eye B is adjusting itself to match eye A.
