From the time a child is born we have to pay attention to the development of the eyes. For many young people, they do not pay attention to some small details of the problem, which is also the reason for the occurrence of nearsightedness of the child in the future. It has been found that most babies are afraid of the dark at night and will cry, many parents in order to let the baby sleep well at night, they turn on the light to sleep, thinking that the baby will not be afraid, and the parents are also convenient to observe the baby sleep clothes, quilt cover or not. This is an extremely unscientific method! When the baby sleeps at night, you must turn off the light, turn off all the lights, and the darker the better. Sleeping with the light on is very unhealthy for infants. The human eye is at rest only when it is completely relaxed, when the pupil is dilated and the ciliary muscles are relaxed. If we turn on the light, due to the effect of light, we can still feel a little bit bright when we close our eyes, the pupil will not be dilated, and the ciliary muscle will not be relaxed. At this point, the human eye is still in a working state. The human brain has gone to sleep, but the eye does not get rest because the ciliary muscle is not relaxed. Since there is light present, the retina perceives light and the retinal cells are not rested. Excessive light stimulation accelerates retinal development, and this also increases the likelihood of becoming nearsighted. For people who are not amblyopic, it is highly unscientific to sleep with the light on. From birth, you can not turn on the light to sleep, we recommend normal people to what age do not turn on the light to sleep. Of course, there are exceptions, that is, patients with high farsightedness and amblyopia, such people can turn on the light to sleep. Some parents turn on the TV all day long in order to make their babies quieter, which is also a very unscientific method. Babies like to watch TV very close to see, due to often look at objects in close proximity, the eyes can not relax, it is easy to fatigue, prone to eye overdevelopment phenomenon, so it should be minimized to the maximum extent possible to see the TV situation. And television will also be some radiation, electromagnetic waves, ultraviolet light and other harmful substances, the eyes also have damage. Parents had better take the baby to more outdoor activities, let the eyes see objects five meters away, so that the eyes can get better exercise. 24 months of infants visual acuity is roughly 0.4 ~ 0.5, at this time the eye movement reflexes to reach a fairly sophisticated degree. 36 months visual acuity is roughly 0.5 ~ 0.7, eye movement reflexes are stable. After ten months of life, babies can walk and talk, and they also start to eat some food, such as fish, shredded meat and so on. Nutritionally speaking, the probability of malnutrition in infants is not high nowadays (except for those who are particularly partial to food). As parents are especially loving and caring, they want to feed their babies with the best food, but are these things good for babies? Here is a special message that the best fish is deep-sea fish, which cannot be farmed and is healthy with less deep-sea pollution. This will also protect the healthy development of the baby’s eyes.
