From
Stereoscopy and the Human Visual System (2013) :
"We may need to be particularly cautious about long-term effects of vergenceaccommodation conflicts on younger children, because their visual systems are still developing. We know of no specific causes for concern at this time, but the research required to identify relevant issues has not yet been done. It is reasonable to assume that vergenceaccommodation coupling exists because it is beneficial, so we should be cautious when systematically disrupting its natural operation. The ZoC could be measured in children in the same way it has been measured in adults. Clearly, however, it would not be acceptable to carry out the long-term experimental studies that would be required to understand any potential long-term effects."

Fine and coarse stereopsis follow different developmental trajectories in children (2012) :
"These results suggest that coarse stereopsis matures before 4 years of age, but fine stereopsis continues to mature into the school-age years. [...] performance was immature until age 12, at the finest disparity tested"
From
Sparing of coarse stereopsis in stereodeficient children with a history of amblyopia (2013) :
"most studies agree that stereoacuity is still immature at 5 years of age and reaches adult levels between 6 and 9 years of age"
