It takes approx. 36-40 weeks for the baby to be fully developed. Before that, the baby is premature and might have to spend some time in an incubator.
Although their eyes begin development during the fifth week of pregnancy, it takes weeks after birth for a baby's eyes to fully develop. At four months' gestation, their eyes are nearly fully formed. From 26 to 28 weeks' gestation, babies keep their eyes open a lot. They can detect light shining directly into the womb, such as when the mother is sunbathing. By the 33rd week of pregnancy, their pupils constrict and dilate, which allows them to better detect light.
