The fetus may be able to see the appearance of the uterus
fetus may be learned before birth. Because enough light can penetrate the abdomen of pregnant women, fetal vision may develop within the last two months of pregnancy.
we already know that the fetus has sense of smell, taste and hearing. Marco Del Giudice of University of Turin in Italy wants to know if there is enough light for the fetus to have vision.
he modeled the amount of light penetrating the normal womb according to the transmission coefficient of biological tissue, ambient light, and the thickness of the abdomen, and found that the 0.1-1% of the ambient light could penetrate the womb of nude women (Developmental Psychology, DOI:10.1002/dev.20506).
in bright sunlight, the light that the fetus receives is comparable to that in the ordinary illuminated room.
