Heads Up! or Box on Neck

[DDL]

If one positions the head so that the eyes are focusing directly ahead at the ball, then shouldn't one have to adjust the eyes to look slightly downward to focus on the inside corner of the ball?

I noticed this the last time I was at the range. At address, my head is looking either at the ball or slightly above it, and my eyes need to point a bit downward to see the inside aft quadrant of the ball. However, during startup, and continuing on throughout the rest of the swing, my eyes refocus back to center, and look at the outside corner of the ball or the back of the ball.

I wonder if one should position the head so that the straight ahead position is slightly downward so that hte inside corner of the ball is the neutral focus position of the eyes.
