Yeah, you are right. Some of them closed their eyes when the baby born, but the eyes some of the new babies are wide open when you are seeing the new world the first time, because they have been looking around in mother's tummy for about 15 weeks before this. If the eyes of the baby are closed when he is born, as usual, it will not take long time to open his eyes because he also wants to know the new environment. If you just put the baby in the room, he will open his eyes within a few days. However, when you put the new-born baby under the sunshine or the strong light, the baby will squint or turn away from the light which will make his eyes feel uncomfortable. If you always see the baby's eyes are closed, that does not mean he do not open the eyes, instead that is just because the baby are asleep when you see.
