Patient's question:
NoDoctor's answer:
The visual development of the fetus is slower than other sensory functions. After the 27th week of pregnancy, the brain of the fetus can perceive external visual stimuli. Before the 30th week of pregnancy, the fetus cannot fix its gaze on a light source, and until the 36th week, the fetus can only respond to light stimulation. Therefore, starting from the 24th week of pregnancy, a flashlight (weak light) should be used as a light source at fixed times when the fetus is awake to illuminate the direction of the fetal head on the mother's abdomen for about 5 minutes each time. At the end, the flashlight can be turned on and off several times in a row to promote the visual health development of the fetus.
