IF she is also hereditary – a child with a nearsighted parent is twice as likely to be hereditary; with two short-sighted parents, this risk is roughly multiplied by six -, myopia is also and above all related to lifestyles. In city dwellers, the risk of being nearsighted is maximum. Indeed, pour que what problems “It does not develop, an individual needs to be subjected to several hours – at least two – of natural radiation per day. Or the current lifestyle forces us to be more and more indoors (transporturi, the work). …)”points out the president of the Syndicat national des ophtalmologistes de France. “In favor of the secretion of dopamine, natural light helps to limit the elongation of the eye and, therefore, to slow down the development or aggravation of vision problems.”researchers from the Ipsos Institute abound in their study.
This need for natural light is particularly intense in children since myopia develops mainly between 5 and 15 years. “This is a time when children need to have more outdoor activities.”assents Thierry Bour.
On the other hand, close vision is constantly in demand today, scientists point out. What to fatigue the eyes and increase the risk of them contracting myopia. As an indication, children between the ages of 3 and 6 spend an average of 3:29 a day on books or screens. A figure that rises to 6:54 for 11-13 year olds. So many activities – including reading when extended – that are particularly demanding on near vision. It should be noted that researchers agree that educational studies and pressure are also two factors that can favor the occurrence and progression of myopia.
