Here is a great video by Coach Patrick Mouratoglou that was posted on his youtube channel on one's dominant eye and technique:

This is something mostly overlooked by the coaches. In fact, a very few coaches even know about this. Usually dominant eye becomes an issue and requires technical correction when one is a cross eye dominant i.e. a right handed player with left eye as dominant one.

Interestingly, Roger Federer is cross eye dominant.
