儿童近视率上升的原因是什么？本文就现代生活方式对儿童视力的影响，以及矫正儿童视力的解决方案展开讨论。

词汇：eye health 眼部健康

How's your eyesight? From the moment we're born, our eyes grow, our vision becomes clearer and some of us will have normal or even 20:20 vision. However, others will become short-sighted and end up wearing glasses or contact lenses to help them see everything clearly. And some experts claim that more of us will be wearing them in the future because of our lifestyle when we were younger.

你的视力怎么样?从我们出生的那一刻起，我们的眼睛就在成长，我们的视力变得更加清晰，我们中的一些人会有正常的甚至20:20的视力。然而，有些人会变得近视，最终戴上眼镜或隐形眼镜来帮助他们看清楚一切。一些专家称，由于我们年轻时的生活方式，未来会有更多的人戴眼镜。

Even today, optometrists are reporting a rise in short-sightedness – also called myopia – in children. The condition can be genetic, but it's also partly being blamed on a number of modern-day factors – particularly children staring at phone screens, computers and game consoles for long periods of time. It's believed myopia also makes them susceptible to secondary eye conditions such as glaucoma, retinal detachment and other visual impairments later in life.

即使在今天，验光师也报告说，儿童近视(也叫近视)的人数在增加。这种情况可能是遗传的，但也部分归咎于许多现代因素——特别是儿童长时间盯着手机屏幕、电脑和游戏机。据信，近视还会使他们在以后的生活中容易患上继发性眼部疾病，如青光眼、视网膜脱离和其他视觉障碍。

Of course, children have had increased screen time due to lockdowns imposed during the Covid pandemic – it's been the only way to access education and communicate with others. But education generally could be blamed for the rise in myopia. Neema Ghorbani-Mojarrad, lecturer at the University of Bradford, told BBC Future website: "We suspect it is reading and spending more time indoors. Every year of education completed increases the expected amount of short-sightedness."

当然，由于Covid - 19大流行期间实施的封锁，孩子们的屏幕时间增加了——这是接受教育和与他人交流的唯一方式。但近视人数的上升通常可以归咎于教育。布拉德福德大学讲师Neema Ghorbani-Mojarrad在接受BBC Future网站采访时表示:“我们怀疑原因是阅读和花更多时间呆在室内。完成教育的每一年都会增加近视的预期数量。”

The problem appears to be more severe in some Asian countries. Some experts say that in these places with huge educational success, children spend more time indoors studying. Therefore, it seems, spending more time outdoors could be good for children's eye health. The UK's College of Optometrists is suggesting parents should get their kids playing outside for two hours a day. Several scientific studies show this can prevent or stop the development of myopia.

这个问题在一些亚洲国家似乎更为严重。一些专家表示，在这些教育取得巨大成功的地方，孩子们花更多的时间在室内学习。因此，花更多的时间在户外可能对孩子的眼睛健康有好处。英国验光师学院建议家长应该让孩子每天在户外玩两个小时。一些科学研究表明，这可以预防或阻止近视的发展。

There's been a focus on using technology, such as laser surgery, for fixing myopia, but for children at least, it seems a dose of daylight and a break from the screen might be part of the solution. Opticians also recommend kids have regular eye tests to identify any problems before they become more severe.

人们一直致力于使用技术手段，如激光手术，来治疗近视，但至少对儿童来说，似乎一剂阳光和远离屏幕可能是解决方案的一部分。验光师还建议孩子们定期做视力检查，在问题变得更严重之前发现问题。
