在线游戏限制将减少童年的近视吗？

Published:

China has recently outlined a new national policy limiting the hours children under 18 can play online games. Gaming for children is now restricted to between 8pm and 9pm, on Friday, Saturday or Sunday and on public holidays. Comparing online gaming to “spiritual opium,” the enforcement applies to hand held gaming, online gaming and phone gaming.1This is to be done by individual login accounts, with real-name verification systems, now a requirement for console and phone gaming in China.

国营中国互联网网络信息中心报道称，中国30％以上的中国儿童遭受了博彩障碍，由世界卫生组织作为新兴条件认可。2该决定在世界上最有利可图的博彩市场之一享有数百万美元的股票价格1and has raised many questions - how will this be successfully implemented? Is this an overstep of government into family choices? This article will primarily address the ocular relationship. Will government regulations in gaming lead to a slowing in the rate of myopia seen in Chinese children?

应该在孩子们视频游戏有限吗？

Restrictions on gaming is not a new concept. Pinball machines were once condemned in 1940s New York, considered to be a waste of time and “insidious nickel stealers” according to a世界经济论坛post. China has tried a similar policy in the past; this is an escalation of a previous rule in 2019, where gaming access to children was limited to only 1.5 hours per day during the school term.

The American Academy of Paediatrics3.and the Australian Government Department of Health4.recommend no more than 2 hours per day on screens outside of school time.The average number of hours spent globally on playing video games is 8.45 hours per week那5.而这并没有考虑社交媒体，电影和视频内容和社交应用程序使用。

在线游戏的负面影响

由于其图形图像，游戏，可以增加幼儿的暴力倾向，这是有限的证据表明这是真实的。在自然界中发表的一项研究，看着游戏对非暴力游戏的严重影响，并通过调查在两个月的比赛中通过调查评估儿童。他们发现大量测试中没有差异，评估两组之间的侵略和移情措施的行为措施。7.

Harvard Health however warns against carpel tunnel, obesity and Internet Gaming Disorder (IGD), which according to the American Journal of Psychiatry affects 0.3% to 1.0% of Americans.8.游戏成瘾可能包括社会退出，关系丧失，较差的教育结果或职业机会或消极情绪状态等问题。9.

这不仅仅是掌握市场份额的游戏。YouTube去年报告说，在渠道上观看超过10亿小时的游戏;孩子们不仅仅是玩游戏，也是花时间看别人玩游戏。虽然屏幕时间和近视之间的联系尚不清楚，但可能由于缺乏客观数据10.我们知道以下内容。

Children who use screens for more than three hours per day are almost four times more likely to be myopic.11.

年龄较小的群体风险更高：6.- to 7-year-old children are five times more likely to be myopic with heavy screen use。Extended screen time has also been linked to eye strain, headaches and dry eye syndrome in both children and adults.12.

What about school performance? Thousands of children were surveyed across middle schools in China examining the relationship between media and technology consumption by teens and performance at school. They found that 62% of children used interactive technology for entertainment, such as online gaming, and 40% of children utilized these systems on school days. There was an adverse, significant association between hours spent on technology and performance at school. Children who use technology for more than an hour on a school night and more than four hours on a weekend had a noticeable decline in their school grades a year later across almost all subjects, and had worse attendance and concentration in class.13.

Will gaming restrictions lead to more outdoor time?

China already had childhood gaming restrictions in place, albeit less severe at 1.5 hours on any day and three hours on holidays, which were instituted in 2019.1Despite this, there's been a steady increase in childhood myopia since, although this is complicated by COVID-19 related home confinement in 2020 which seems to have had greatest impact on 6- to 8-year-old rates of myopia.14.

The only way to really answer this question is to look at studies which investigate interactions between near work and outdoor time. The Sydney Myopia Study showed a stronger positive impact of outdoor time than negative impact of near work time on development of myopia, when the time spent outdoors was high (more than 3 hours per day).15.这似乎表明了这一点大量的户外时间比在靠近工作的时间更重要，这是父母与孩子屏幕时间挣扎的好消息。188足彩比分直播

In another study involving European children, though, when children had low amounts of near work time (less than 1 hour per day), increasing amounts of near work had a larger impact on myopia onset.This is the flip-side of the message above: with low outdoor time, the increased near work time carries a greater risk of myopia.16.The latter study also found that the negative effect of combined near work time was decreased by the positive effect of outdoor exposure.

The sum total? More time spent on reading and screens can be balanced by outdoor time, but only if the outdoor time is high, averaging at least 2-3 hours per day.15,16.

Are there any positive aspects to online gaming?

过去两年带来了一系列独特的挑战，具有广泛的锁定，社会疏散和在线教育。在线游戏和社交媒体已经提供了一团和沟通，即使在物理上分开。世界经济论坛报告了一个survey表明,64%的父母说他们的孩子dren’s screen media usage lead to stronger friendship and connections with peers. Gaming has also seen recent applications in improving cognition in Attention Deficit Hyperactivity Disorder (ADHD) and decreasing symptoms in both ADHD and Autism Spectrum Disorder.17.那18.

“Teenagers are the future” said an unnamed government source regarding China's gaming restrictions,1他们当然是对的。虽然技术肯定丰富了我们的生活，特别是在最近的社会遥远的过去，新科技挑战并支持儿童的身心健康必须是优先事项。视频和在线游戏限制是否提供了积极的框架？时间会告诉。
