离不开手机电脑？小心“数码视觉疲劳”
<p>由于电脑、掌上电脑、智能手机等使用人群不断增大，电脑等数码设备使用和屏幕阅读量的增加，导致中国国内每年有近40万人到眼科医院做检查。使用数码设备的工作者接触到屏幕的机会比直接接触的太阳光高出4倍。紧盯着屏幕1.5小时以上的人群中就有83.6%可能会患上数码视觉疲劳。</p><p><span word="Do">Do</span> <span word="you">you</span> <span word="have">have</span> <span word="a">a</span> <span word="crick">crick</span> <span word="in">in</span> <span word="your">your</span> <span word="neck">neck</span>, <span word="a">a</span> <span word="sore">sore</span> <span word="shoulder">shoulder</span>, <span word="or">or</span> <span word="an">an</span> <span word="aching">aching</span> <span word="back">back</span>? <span word="Maybe">Maybe</span> <span word="your">your</span> <span word="eyes">eyes</span> <span word="are">are</span> <span word="dry">dry</span>, <span word="your">your</span> <span word="vision">vision</span> <span word="is">is</span> <span word="blurry">blurry</span> <span word="at">at</span> <span word="the">the</span> <span word="end">end</span> <span word="of">of</span> <span word="the">the</span> <span word="day">day</span>, <span word="or">or</span> <span word="you">you</span> <span word="have">have</span> <span word="a">a</span> <span word="persistent">persistent</span> <span word="headache">headache</span> <span word="that">that</span> <span word="just">just</span> <span word="won">won</span>&<span word="rsquo">rsquo</span>;<span word="t">t</span> <span word="quit">quit</span>? <span word="These">These</span> <span word="are">are</span> <span word="all">all</span> <span word="symptoms">symptoms</span> <span word="of">of</span> <span word="digital">digital</span> <span word="eye">eye</span> <span word="strain">strain</span>, <span word="reported">reported</span> <span word="by">by</span> 65 <span word="percent">percent</span> <span word="of">of</span> <span word="Americans">Americans</span>.</p><p>有没有觉得脖子僵硬，肩背酸痛？一天下来也许你觉得眼睛干涩，视力模糊，或者感觉持续性头痛？这些都是&<span word="ldquo">ldquo</span>;数码视觉疲劳的症状。据报告有65%的美国人患有&<span word="ldquo">ldquo</span>;数码视觉疲劳。</p><p><span word="For">For</span> <span word="many">many</span> <span word="of">of</span> <span word="us">us</span>, <span word="it">it</span> <span word="may">may</span> <span word="feel">feel</span> <span word="as">as</span> <span word="though">though</span> <span word="most">most</span> <span word="of">of</span> <span word="our">our</span> <span word="day">day</span> <span word="is">is</span> <span word="spent">spent</span> <span word="staring">staring</span> <span word="at">at</span> <span word="one">one</span> <span word="screen">screen</span> <span word="or">or</span> <span word="another">another</span>, <span word="and">and</span> <span word="it">it</span> <span word="could">could</span> <span word="be">be</span> <span word="taking">taking</span> <span word="a">a</span> <span word="toll">toll</span> <span word="on">on</span> <span word="our">our</span> <span word="eyesight">eyesight</span>. <span word="More">More</span> <span word="than">than</span> 10,000 <span word="adults">adults</span> <span word="were">were</span> <span word="surveyed">surveyed</span> <span word="for">for</span> <span word="the">the</span> <span word="report">report</span> <span word="and">and</span> <span word="it">it</span> <span word="found">found</span> <span word="that">that</span> 90 <span word="percent">percent</span> <span word="of">of</span> <span word="Americans">Americans</span> <span word="use">use</span> <span word="digital">digital</span> <span word="devices">devices</span> <span word="for">for</span> <span word="at">at</span> <span word="least">least</span> <span word="two">two</span> <span word="hours">hours</span> <span word="a">a</span> <span word="day">day</span>, 60 <span word="percent">percent</span> <span word="use">use</span> <span word="them">them</span> <span word="for">for</span> <span word="five">five</span> <span word="or">or</span> <span word="more">more</span> <span word="hours">hours</span> <span word="a">a</span> <span word="day">day</span>, <span word="and">and</span> 70 <span word="percent">percent</span> <span word="use">use</span> <span word="two">two</span> <span word="or">or</span> <span word="more">more</span> <span word="devices">devices</span> <span word="at">at</span> <span word="once">once</span>. <span word="For">For</span> <span word="those">those</span> <span word="of">of</span> <span word="you">you</span> <span word="reading">reading</span> <span word="this">this</span> <span word="on">on</span> <span word="your">your</span> <span word="phone">phone</span> <span word="in">in</span> <span word="front">front</span> <span word="of">of</span> <span word="the">the</span> <span word="TV">TV</span>, <span word="that">that</span> <span word="will">will</span> <span word="come">come</span> <span word="as">as</span> <span word="little">little</span> <span word="surprise">surprise</span>.</p><p>对许多人来说，一天中大部分时间都在盯着这个或那个屏幕，这非常损害视力。上文中提到的报告中，共有一万名美国成年人参与了调查，结果显示，其中90%每天使用数码设备的时间至少有两小时，60%的受访者使用时间达5小时以上，70%的受访者每次要盯着两个屏幕看。对那些正看着电视刷手机的人们来说，这丝毫不让人惊讶。</p>
