[[f.lux]]是一个[[跨平台]]的[[计算机程序]]，根据一天的地点和时间调整显示器的[[色温]]。软件的目的是减少夜间使用时的眼睛疲劳和[[昼夜节律]]的中断。<ref name=":0">{{cite web|last1 = Zukerman|first1 = Erez|title = Review: f.lux makes your computer usable at night|url = http://www.pcworld.com/article/2056895/review-f-lux-makes-your-computer-usable-at-night.html|accessdate = 3 March 2015|website = [[PC World]]|date = October 31, 2013|archive-date = 2017-09-01|archive-url = https://web.archive.org/web/20170901151211/http://www.pcworld.com/article/2056895/review-f-lux-makes-your-computer-usable-at-night.html|dead-url = no}}</ref><ref name=":1">{{cite web|last1 = Tanous|first1 = Jim|title = Save Your Eyes and Improve Your Sleep with f.lux for OS X and Windows|url = http://www.tekrevue.com/f-lux-review/|accessdate = January 15, 2016|website = TekRevue|date = October 15, 2014|archive-date = 2018-08-30|archive-url = https://web.archive.org/web/20180830041323/https://www.tekrevue.com/f-lux-review/|dead-url = no}}</ref>

== 兼容性 ==
该程序可运行在 [[Microsoft Windows]], [[macOS]] 和 [[Linux]]。也可在iOS设备上运行，但需要越狱。<ref name=":2">{{cite web|last1 = Hoffman|first1 = Chris|title = Reduce Eye Strain and Get Better Sleep by Using f.lux on Your Computer|url = http://www.howtogeek.com/199303/reduce-eye-strain-and-get-better-sleep-by-using-f.lux-on-your-computer/|accessdate = January 15, 2016|website = How-To Geek|date = October 23, 2014|archive-date = 2018-02-19|archive-url = https://web.archive.org/web/20180219031230/https://www.howtogeek.com/199303/reduce-eye-strain-and-get-better-sleep-by-using-f.lux-on-your-computer/|dead-url = no}}</ref> 由于使用了限制的开发工具，苹果[[App Store (iOS/iPadOS)|App Store]]不允许该应用加入其中。<ref>{{Cite news|title = Apple promises a good night's sleep with new iPhone feature|url = https://www.theguardian.com/technology/2016/jan/12/apple-good-sleep-new-iphone-feature-night-shift|newspaper = [[The Guardian]]|date = January 12, 2016|access-date = January 20, 2016|first = Alex|last = Hern|archive-date = 2018-02-18|archive-url = https://web.archive.org/web/20180218210356/https://www.theguardian.com/technology/2016/jan/12/apple-good-sleep-new-iphone-feature-night-shift|dead-url = no}}</ref>[[蘋果公司|苹果公司]]宣布了一项类似的功能，称为[[夜览 (软件)|夜览]]，在[[iOS 9]].3中，开发人员呼吁苹果提供开发工具并允许其应用程序进入App Store。<ref>{{Cite web|title = F.lux Asks Apple To Let Its Screen Color Adjustment App Back Into App Store|url = https://techcrunch.com/2016/01/15/f-lux-asks-apple-to-let-its-screen-brightness-app-back-into-app-store/|website = TechCrunch|access-date = January 20, 2016|first = Sarah|last = Perez|date = January 15, 2016|archive-date = 2018-01-16|archive-url = https://web.archive.org/web/20180116144140/https://techcrunch.com/2016/01/15/f-lux-asks-apple-to-let-its-screen-brightness-app-back-into-app-store/|dead-url = no}}</ref>Android的预览版可用。<ref>{{Cite web|url = https://justgetflux.com/|title = f.lux Home Page|access-date = September 21, 2016|website = f.lux|archive-date = 2018-02-17|archive-url = https://web.archive.org/web/20180217204954/https://justgetflux.com/|dead-url = yes}}</ref>

== 功能 ==
安装后，用户可以根据地理坐标，邮政编码或位置名称选择一个位置。然后，程序会根据所选位置的日出和日落，自动将设备显示器的色温校准到当天的时间。在日落时，它会逐渐将色温变为较暖的颜色，并在日出时恢复原来的颜色。<ref name=":0" /><ref name=":1" />

用户可以从各种颜色配置文件和预定义的温度值中进行选择。他们还可以修改程序对于特定节目或活动的行为，包括电影模式，这会减少2.5小时的红色调，以及不影响夜间适应视力的暗室模式。<ref name=":0" /><ref name=":1" />

时间可以在f.lux上倒置，以便PC在白天提供温暖的照明（对于夜间工作的人）。<ref>{{cite web |url=https://justgetflux.com/faq.html |title=f.lux: F.A.Q. - I work nights. How do I flip the day and night settings? |website=justgetflux.com |date= |author= |accessdate=31 October 2016 |archive-date=2018-02-16 |archive-url=https://web.archive.org/web/20180216065604/https://justgetflux.com/faq.html |dead-url=no }}</ref>

该程序可以控制飞利浦Hue LED照明，使房屋灯光的色温符合f.lux的设置。 <ref>{{cite web |url=https://justgetflux.com/news/pages/bigupdate/ |title=f.lux has been updated to a new version |website=justgetflux.com |date= |author= |accessdate=31 October 2016 |archive-date=2018-05-19 |archive-url=https://web.archive.org/web/20180519005852/https://justgetflux.com/news/pages/bigupdate/ |dead-url=no }}</ref>
== 效果 ==
f.lux支持者推测，改变显示器的色温以减少夜间白蓝光的突出将提高睡眠的有效性。夜间减少蓝光照射与褪黑激素分泌增加有关。<ref>{{Cite journal|title = Effects of Lights of Different Color Temperature on the Nocturnal Changes in Core Temperature and Melatonin in Humans|date = 1996|journal = Journal of Physiological Anthropology|last2 = Hiromi|first = Morita|last = Takeshi|first2 = Tokura|issue = 5|volume = 15|pages = 243–6|pmid=8979406}}</ref>

尽管开发者在其网站上提供了相关研究的列表，但该程序本身没有经过科学测试以确定其功效。尽管如此，技术记者，博客和用户对f.lux提供了广泛而积极的评价。<ref name=":0" /><ref name=":1" /><ref name=":2" />
