引言

一项发表在《英国眼科杂志》上的全球分析显示,儿童视力下降问题正日益恶化,全球每三个儿童中就有一个近视或看不清楚远处的东西。这一趋势在COVID-19大流行期间尤为明显,防疫措施导致孩子们花更多时间在屏幕上,而户外活动时间减少。

研究发现

这项研究调查了六大洲50个国家的500多万名儿童和青少年。研究发现,从1990年到2023年,近视率增加了两倍,上升到36%。亚洲的近视率最高,日本和韩国分别有85%和73%的儿童近视,中国和俄罗斯的近视率也超过了40%。

影响因素

研究人员指出,近视的发生与多种因素有关,包括遗传、过早接受教育、长时间使用电子屏幕等。东亚地区儿童近视率高的原因之一是,这些地区的儿童从两岁开始就接受教育,导致他们在幼年时期用眼过度。

防治措施

英国眼科专家建议,儿童每天至少应在户外活动两个小时,尤其是7到9岁的儿童,以降低近视的几率。此外,家长应定期带孩子进行视力检查,并注意近视的家族遗传倾向。

预测与展望

研究预测,到2050年,全球一半以上的青少年将受到近视的影响。女孩和年轻女性的发病率可能高于男孩和年轻男性。英国眼科专家呼吁,各国政府应采取有效措施,预防和控制儿童近视的发生。

结语

儿童近视问题已成为全球性的健康问题,我们必须高度重视并采取有效措施,以降低儿童近视的发生率,保护他们的视力健康。
