In 2010 I visited a trade fair where Sony presented a hardware/software tool for on set to predict and manage the 3D effect. Indeed to prevent eyestrain.
Other reasons for that strain: imperfect alignement, non sychronous video signals and unequal focal points.
Sadly, I don't remember the name of this thing, but it was meant to be used for on set real time analysis.

It has been too long ago.
I vaguely remember that 2 diverging cameras will produce headache, because it 'forces' your eyes to diverge, which is impossible for most people.
While converging is less likely to be problem, but still not without a risk.
And something about the distances between the lenses: it influences depth and percieved scale, if I remember correctly.
