Of course the question was how can they tell which the baby is seeing?
Because the baby can't control the eye muscles well the image might be
either blurry or jittery or both.  So when they show the picture that the
baby sees an out of focus world, can they be sure that is what the baby sees
or is it jittery.  Both effects would tend to prevent the baby from being
able to percieve objects well.  They could look through the baby's eye to
try to figure out what the baby can focus on, but they can't actually sample
what the baby is seeing.

Getting the data is fairly difficult because of the problem of doing ethical
experiments.

Most optomotrists are actually in a sense engineers or technicians, and not
really scientists.
