The scientists hypothesized that a special kind of fat, P fat, is necessary for the development of eyesight. They observed that babies fed with formula low in P fat had poorer eyesight than those fed with breast milk. The content of P fat in breast milk is high
they put forward the above hypothesis. In addition, they also found that babies born 5-6 weeks prematurely have poorer eyesight than full-term babies.
The mother's poor eyesight does not lead to the baby's poor eyesight.
