Myopia in young children is related to lighting Babies are young and many parents like to sleep with the lights on at night for fear that their children will be afraid of the dark or to make it easier to take care of them. But did you know that this kind of care from you may leave your baby with hidden vision problems. What is this all about? A study in the United States once found that around the age of 2 years is an important period of eye development, and the association between the light source of sleep and vision at this time is very close. The survey showed that if the child sleeps in a dark room before the age of 2, then the proportion of myopia is 10%; if the child sleeps in a room with a small night light before the age of 2, the proportion of myopia is 34%; if the child sleeps in a room with a large light before the age of 2, the proportion of myopia is 55%. So parents should pay enough attention to the light environment in which children live, especially the indoor light environment, to avoid unnecessary excessive light. For children who are afraid of the dark, they should avoid the habit of sleeping in the light when they are young, and parents can sleep with their children and turn off the lights when they fall asleep, while avoiding direct light on the child’s eyes. The common misconceptions about myopia prevention Myth 1: Everything is fine if you wear glasses Treating myopia is never fine if you wear glasses. The prevention of myopia can be summed up in the words “pay attention to the distance of near eye use” and “reduce the time of continuous near eye use”. The “close eye distance” means that the distance between the eyes and books and desktops should not be less than 33 cm. “Reduce the time of continuous close eye use” means that the duration of reading should not exceed one hour, and that you should take off your glasses and look into the distance during the interval to avoid excessive eye use, which may increase the degree of myopia. In addition, parents should take a closer look at their child’s desk and chair match during parent-teacher conferences. Myth 2: Glasses can’t be taken off if you wear them. First of all, it should be clear that myopia has real myopia and pseudomyopia, and real myopia is difficult to recover. Pseudomyopia is possible to recover, but the degree of recovery depends on the proportion of pseudomyopia in myopia, for example, there are 100 degrees of myopia, of which only 50 degrees may be pseudomyopia, wearing glasses is also difficult to recover. Only 100% of pseudomyopia is likely to be recovered. Myth 3: Glasses are unchanging A pair of glasses with the right fit can be measured by several criteria: the error of luminosity should not be greater than 25 degrees, the error of pupil distance should not be greater than 3 mm, the error of pupil height should not be greater than 2 mm, if wear fatigue, vertigo and long time does not disappear, this pair of glasses is not suitable for you. But a good pair of glasses is not the same as being able to get rid of them once and for all, glasses also need frequent maintenance, usually do not use clothes or napkins to wipe the lenses, take off and wear glasses with both hands, one-handed uneven force, the frame is easy to deform, there are problems should go to the regular prescription place to debug, while wearing glasses is best every 3 months or half a year to check to see if the degree of change.
