I know the post is a bit old but thought I would share how I fix the lazy eye problem, in case anyone else needs the solution.
With the person selected, go to auto Behaviors -> Eye Control
Make sure "Eyes look at" -> Target is selected.
Move the EyeTarget to a position that causes a problem with the eyes
Adjust setting one at a time, trial and error until problem goes away. I start with left/right angle adjust and max angles but every model is different.
When you think it looks good, remember to move the eyetarget around. Try near and far targets to make sure you didn't introduce a new problem.
Also, the solution may be a compromise. It might not be perfect in every case, find a set of settings that you can live with.
Hope this helps someone.
