In general, most newborns will open their eyes about 2-3 days after birth, with individual differences in the exact time of opening for each newborn, but no later than 10 days at most. Some newborns will open their eyes naturally within a few hours after birth, while some may be reluctant to open their eyes because the light in the room is too strong and irritates their eyes too much. Because newborns are sensitive to light, they generally sleep with their eyes closed and open their eyes for a relatively short period of time, so sometimes parents may not notice. Under normal circumstances, newborns will open their eyes 2-3 days after birth, and no later than 10 days. In the case of premature babies or newborns with cerebral blood supply deficiency, the time to open the eyes will be relatively longer. If the newborn does not open its eyes, it should not be forced to open its eyes, so as not to affect its eye development.
