1) I have the sameproblem with eyes on my new iMac. After about 5 minutes I feel eye strain. Alsomy 2 years old daughter feels pain in her eyes after a few minutes and shedon't want to see new fairy tales. By: skulo
对於我的新imac, 我也面对相同的问题. 在5分钟后我感到眼睛疲劳. 而且我的2岁大女儿在几分钟后感到眼睛痛楚, 她不愿再看新的童话故事.

2) Thereis one relatively serious con of the new LED backlit displays in the new MacBook Pros that seems tonot get too much mention in the media. About a month ago I bought a new MacBookPro to replace my standard white MacBook. One feature of the MacBook Pro that Iwas unaware of was the introduction of the LED backlit display to replace the CCFL backlight.
新的macbook pros的led背光源这个相对严重的坏处似乎没有被媒体提及. 约一个月前我买了新的macbook pro去换掉旧的标准白色macbook.Macbook pro 的一个特点我没有留意到的是所介绍的led背光源显示去代替ccfl背光源.
Once I started using my new laptop for long periods of time, I noticed severeeye strain and minor symptoms almost similar to motion sickness.
当我开始用我的新电脑工作一段长时间, 我注意到严重的眼睛疲劳及轻微的晕眩症状.

3) This is interesting. I recently spent intensiveamounts of time in front of my MBP while working on my Thesis. I noticed by theend of the day, I had to boost the zoom on the document to 150% at times aseverything was blurry.
这很有趣. 我最近用大量时间在mbp(电脑名字缩写)工作. 我发现在傍晚,我须要多次把文件放大至150%, 因为全部东西都很模糊.

4) I havethe same problem. I just got a new Macbook pro 15" two weeks ago. I neverhad a macbook before, and was used to work for hours with different notebooks(with different kind of linux flavors). After one hour my eyes start to hurt,first I thought maybe the fonts are too small, or the backlight too bright. Butchanging this didn't help.
我有相同的问题. 我刚在2星期前拥有macbookpro 15”. 我之前没拥有过macbook, 及以前习惯使用不同的笔记型电脑长时间工作(配置不同的linux喜好). 一小时后我的眼睛开始痛,最初我想或许是字体太小, 或是背光源太强. 但调节后也没有帮助.


Then i searched the internet, found several people reportingthe same issues with the LEDbacklight.
然后我在网上寻找, 发现好一些人在报告有关led背光源的相同问题.

6) Ibought a new 15" MBP on November 4, spent the evening migrating, andwithin 10 minutes of actually using it on the 5th I developed severe motionsickness symptoms. Within 30 minutes my eyes hurt. I tried to work through thisand failed absolutely. The MBP was returned to the Apple Store on November 10.
我在11月4日买新的15”mbp,用了10分钟后, 在5号我便有严重的晕眩症状. 在30分钟内我的眼睛感到痛.我尝试克服过去, 但彻底的失败. 那个mbp在11月10日送回apple store.

7) I justgot my MBP yesterday and I've already spent over an hour on forums trying tofind out about this because the problem is so bad for me. It takes less than 5minutes for a headache to develop.
我昨天买了mbp, 但我现在已经用了超过一小时在讨论区上尝试找寻这些,因为对我来说问题很严重. 它只须用小於5分钟去引致头痛的产生.

其实LED 都系大势

以前电视一系LCD一系等离子
宜家都好多都用晒LED背光，又话耐用啲又话点

LED都有唔刺眼既, 但真系要试过先知.

例如: iphone 4 及 4s 都系用 LED backlit, 但系人地话4无事, 而4s就刺眼. http://mobile.discuss.com.hk/viewthread.php?tid=23243231 [最尾个段, 系英文讨论区转贴, 总共133页]

但系4同4s都系用紧 “LED-backlit IPS LCD”. 有人话4 无事, 而4打后就….你可以入去睇下.

如果你考虑买LED电视, 建议你真系要做好资料搜集先去, 你可以搜寻 LED tv, eye strain, headache, fatique, eye hurt, return, blurred 等字眼, 将会出现一大堆分享.
eye strain = 眼睛疲劳
headache = 头痛
fatique = 疲劳
eye hurt = 眼痛
return = 退回
blurred vision = 视力模糊; within minutes = 几分钟内

其实会唔会系主观感觉或者系次品。


我自己都系MacBook Pro Retina，日日对住十几个钟都无问题。 我亮度较低。

很大可能不会, 因为很多人也分享了对LED Backlit 的同感, https://discussions.apple.com/message/22432852#22432852

洗 Q 做咁多 research 咩。但又唔觉好 academic。
去铺头对住一两粒钟，盲唔盲好快知。
Apple mon 由 '08-present，卖一千几佰万部，有几%人嘈只可说声遗憾。

多谢回覆, 我也搜寻了你的post, 似乎是apple迷.

可能只系少部分人眼睛本身就唔可以望光太耐

就好似有啲人见到五颜六色动画咁就会晕

我谂我对住mac过千小时以上…依家有近视系唔系有得索偿...

其实你系呢度都预左有Apple迷

而且我觉得佢都够中肯，同理性 唔系痴左线死都Hard Sell Apple 个啲人

目前的电脑LCD大都是用LED背光，传统的CCFL几乎被淘汰了。
LED俱有省电、亮度足、便宜的优点，但是.....目前LED背光都太刺眼，太萤光

同样是LED，为何apple的电脑就不会萤光和刺眼，我曾经询问过维修电脑人员，他说「为了结省成本，目前市面上LED背光用的都是便宜的蓝色LED，然后调成"近似"白光的LED。而apple系统用的是较贵纯白色的LED，看起来效果当然有差」
说穿了，一切都是cost down的后果啊.... 把PowerMac和一般PC笔电放在一起，Mac显示颜色真的把其他PC打到趴。而且呈现的白色是舒服的白色，而不是PC那种惨白色。
