IF it is also hereditary – a child with a myopic parent is twice as likely to be so; with two myopic parents, this risk is roughly speaking multiplied by six -, myopia is also and above all linked to lifestyles. Among city dwellers, the risk of being nearsighted is greatest. Indeed, for this disorder “does not develop, an individual needs to be subjected to several hours – at least two – of natural radiation per day. However, the current way of life obliges us to be more and more inside (transport, work …)”underlines the president of the National Union of Ophthalmologists of France. “By promoting the secretion of dopamine, natural light would help limit the elongation of the eye and therefore slow down the development or aggravation of this vision disorder”abound the researchers of the Ipsos institute in their study.
This need for natural light is particularly intense in children since myopia essentially develops between the ages of 5 and 15. “It’s a time when you have to make sure that children have more outdoor activities”asserts Thierry Bour.
In addition, near vision is constantly in demand today, point out the scientists. What tire the eyes and increase the risk that they contract myopia. As an indication, children between 3 and 6 years old spend an average of 3h29 per day on books or screens. A figure that rises to 6:54 for 11-13 year olds. So many activities – including reading when it is prolonged – which particularly solicit near vision. It should be noted that researchers agree on the fact that studies and educational pressure are also two factors that can promote the onset and progression of myopia.
