我们大多数人都“依附”于智能手机——这些技术奇迹让几乎每个人都一遍又一遍地看着它们：在工作中、在床上、在地铁里、在飞机上、咖啡馆，无处不在。除了它们给世界带来的所有好处之外，智能手机还具有使我们的眼睛疲劳和让我们无法入睡的丑陋力量。这主要是因为我们使用智能手机并一直看着它们的屏幕直到我们入睡。这不好，因为它们的屏幕发出的蓝光会影响我们的昼夜节律并削弱我们入睡的能力。除非您打算不使用Android睡前几个小时使用智能手机或平板电脑，减少其发出的蓝光的有害影响的解决方案是安装和使用过滤它的应用程序。我们尝试了一些最流行的适用于Android的(Android)Night Light应用程序。以下是我们认为最好的：
1.暮光之城(Twilight)（蓝光(Blue)过滤器，更好的睡眠）
您可以在Google Play 商店(Google Play Store)中找到用于过滤蓝光的最佳“夜灯”应用之一，称为Twilight。为了阻挡您的Android(Android)智能手机或平板电脑发出的蓝光，它会在您的屏幕上应用红色滤镜。此外，它还可以调暗屏幕亮度，以进一步减轻眼睛的压力。过滤器可以在晚上自动应用，您可以在您选择的时间安排它，您也可以手动打开或关闭它。如果您选择在夜间自动启用过滤器，Twilight可以根据您当地的日落和日出时间来做到这一点，非常棒。

2. sFilter - 蓝光滤镜
sFilter - 蓝光过滤器(sFilter - Blue Light Filter)是另一个流行的“夜灯”应用程序，可让您在需要时手动打开蓝光过滤器。此外，它还允许您设置在手动指定时间打开和关闭蓝光过滤器的时间表。该应用程序支持您可以根据自己的喜好选择的各种颜色过滤器，以及不透明度和亮度级别的控制。
我们赞赏并且相信你们中的许多人也会这样做的一件事是sFilter - Blue Light Filter还有一个小部件，您可以使用它来快速打开或关闭过滤器。该小部件浮动在您的Android屏幕上可能拥有的所有其他内容之上，因此您无需切换应用程序即可启用或禁用“夜灯”模式。

3.蓝光滤镜(Blue Light Filter)-夜间模式(Night Mode)，夜班(Night Shift)
另一个可以限制Android(Android)智能手机或平板电脑发出的蓝光的好选择是蓝光过滤器 - 夜间模式，夜班(Blue Light Filter - Night Mode, Night Shift)。它可以调暗屏幕亮度并应用屏幕滤镜，将显示的颜色更改为感觉更自然的颜色。事实上，您甚至可以选择您希望应用使用的自然光类型：夜班、烛光、黎明、白炽灯、荧光灯(Night shift, Candlelight, Dawn, Incandescent Lamp, Fluorescent Lamp)或阳光(Sunlight)。当然，如果您愿意，也可以手动调整滤镜强度。

4.护眼(Eye Care)蓝光滤镜(Bluelight Filter)-自动(Auto)屏幕滤镜
用于眼睛护理的蓝光过滤器 - 自动屏幕过滤器(Bluelight Filter for Eye Care - Auto screen filter)是一款简单的“夜灯”应用程序，它不会使屏幕亮度变暗以保护您的眼睛。它只会将显示的颜色更改为较暖的颜色，蓝色较少。它可以手动打开和关闭，您可以调整应用滤镜的强度，还可以选择使用七种预定义滤镜颜色中的一种。

5. 蓝光滤镜 - 夜间模式
蓝光过滤器 - 夜间模式(Bluelight Filter - Night Mode)应用程序可能是最直接的Android应用程序，旨在对抗蓝光，仅此而已。它提供五种不同的滤镜颜色，您可以使用滑块来增加或减少滤镜强度，但这就是它的全部内容。没有自动化选项，没有屏幕变暗，不幸的是，如果您使用免费版本，还有半屏广告。但是，它易于使用，并且运行良好，因此它是比其他“夜灯”应用程序更好的选择。

6.夜猫子(Night Owl)-屏幕调光和(Screen Dimmer)夜间模式(Night Mode)
Night Owl - Screen Dimmer & Night Mode是一款Android应用程序，为了减少设备发出的蓝光，它会调暗屏幕背光并在其上应用滤色器。它可以手动打开，也可以根据您选择的时间表自动打开。它可以在晚上自动打开，使用您所在位置的日出和日落时间，但不幸的是，这是一项高级功能，只有您购买该应用程序才能使用。
我们发现有趣的一件事是它为您提供了使用“高级滤镜”的选项，这意味着您可以手动选择“夜灯”滤镜的红色、绿色和蓝色值。

7. Android智能手机内置的夜灯模式(Night Light)
最后但同样重要的是，还有大多数运行Android 7 (Android 7) Nougat或更新版本的智能手机的内置选项。Android使用Night Light作为其蓝光过滤功能的名称，但一些制造商喜欢更改名称，因此您可能会发现它标记为蓝光过滤器、舒适视图、夜间模式、护眼、夜间显示(Blue Light Filter, Comfort View, Night Mode, Eye Care, Night Display,)等。 Android，打开(open the )设置(Settings)并导航到显示(Display)设置。如果您在那里看不到它，请尝试使用搜索(Search)来查找我们提到的“夜灯”术语之一。
例如，在我的华为 P20(Huawei P20)上，内置的蓝光滤镜选项位于Settings -> Display & brightness -> Colour & eye comfort -> Eye Comfort -> Blue Light Filter。在那里，我可以手动启用或禁用“夜灯”模式，设置自动打开和关闭的时间表，以及调整它使用的色温。
您是否使用夜灯应用来过滤Android上的蓝光？
我们在本文中为您推荐的应用程序都擅长其工作。它们都能够限制您的Android(Android)智能手机或平板电脑发出的蓝光量。但是，其中一些提供了比其他更多的选项和设置。我们相信您会找到最适合您的。试一试，保留你最喜欢的那个。然后，在下面的评论中与我们分享您的选择。
6+ best Night Light apps for Android -
Most of us are "attachеd" to smartphones - those technological wonders that make almoѕt every person look at them over and over again: at wоrk, in bed, in the subway, in airplanes, cafes, everywhere. Besides all the good they bring to the world, smartphones also have thе ugly powеr of tiring our eyes and keeping us from sleeрing well. This happens mostly because wе use our smartphones and look at their screens right until we fall asleep. That's not good because the blue light theіr screеns emit affеcts our circadian rhythm and impaіrѕ our ability to fall asleep. Unless you plan on not using your Αndroid smartphоne or tablet for a few hours before you go to bed, a solution to rеduce the harmful effects of the blue light emitted by it is to instаll and use an app that filters іt. We tried some of the most popular Night Light apps for Android. Here are those which we consider the best:
1. Twilight (Blue light filter for better sleep)
One of the best "night light" apps you'll find in the Google Play Store for filtering blue light is called Twilight. To block the blue light emitted by your Android smartphone or tablet, it applies a red filter over your screen. Additionally, it can also dim the screen brightness to reduce the strain on your eyes even more. The filter can be applied automatically at night, you can schedule it during the times you choose, and you can also turn it on or off manually. If you choose to automatically enable the filter at night, Twilight can do that based on your local sunset and sunrise times, which is excellent.

2. sFilter - Blue Light Filter
sFilter - Blue Light Filter is yet another popular "night light" app that lets you turn on a blue light filter manually, whenever you feel you need it. Furthermore, it also allows you to set a schedule for turning the blue light filter on and off at manually specified times. The app supports various color filters that you can select depending on your preferences, as well as controls for opacity and brightness levels.
One thing that we appreciated and we're sure many of you will do too is the fact that sFilter - Blue Light Filter also has a widget that you can use to quickly turn the filter on or off. The widget floats on top of everything else you might have on your Android's screen, so you don't have to switch apps to enable or disable the "night light" mode.

3. Blue Light Filter - Night Mode, Night Shift
Another good alternative that can limit the blue light emitted by your Android smartphone or tablet is Blue Light Filter - Night Mode, Night Shift. It can dim your screen's brightness and apply a screen filter that changes the colors displayed into colors that feel more natural. In fact, you can even choose the type of natural light that you want the app to use: Night shift, Candlelight, Dawn, Incandescent Lamp, Fluorescent Lamp, or Sunlight. Of course, you can also adjust the filter intensity manually if you prefer.

4. Bluelight Filter for Eye Care - Auto screen filter
Bluelight Filter for Eye Care - Auto screen filter is a simple "night light" app that doesn't dim your screen's brightness to protect your eyes. It only changes the colors displayed to warmer ones, with less blue. It can be turned on and off manually, you can adjust the intensity of the filter applied, and you can also choose to use one of the seven predefined filter colors.

5. Bluelight Filter - Night Mode
Possibly the most straightforward Android app designed to fight blue light, the Bluelight Filter - Night Mode app does what it says and nothing more. It offers five different filter colors, and you can use a slider to increase or decrease the filter intensity, but that's about all there is to it. No automation options, no screen dimming, and, unfortunately, half a screen of ads, if you use the free version. However, it's easy to use, and it works well, so it's a better option than other "night light" apps.

6. Night Owl - Screen Dimmer & Night Mode
Night Owl - Screen Dimmer & Night Mode is an Android app that, in order to reduce the blue light emitted by your device, dims the backlight of the screen and also applies a color filter on it. It can be turned on manually as well as automatically based on a schedule of your choosing. It is able to turn on automatically at night, using the sunrise and sunset times of your location, but, unfortunately, this is a premium feature available only if you buy the app.
One thing that we found interesting is the fact that it offers you the option to use an "advanced filter," meaning that you can manually choose the red, green, and blue colors values of the "night light" filter.

7. The Night Light mode that's built-in on your Android smartphone
Last but not least, there's also the built-in option that most smartphones running Android 7 Nougat or newer have. Android uses Night Light as the name for its blue light filtering feature but some manufacturers like changing names, so you might find it labeled as Blue Light Filter, Comfort View, Night Mode, Eye Care, Night Display, etc. To find it on your Android, open the Settings and navigate to the Display settings. If you don't see it there, try to use the Search to find one of the "night light" terms that we've mentioned.
For example, on my Huawei P20, the built-in blue light filter options are found in Settings -> Display & brightness -> Colour & eye comfort -> Eye Comfort -> Blue Light Filter. There, I can enable or disable the "night light" mode manually, set a schedule for when it should turn on and off automatically, as well as adjust the color temperature used by it.
Do you use a night light app to filter blue light on your Android?
The apps we recommended for you in this article are all good at their job. They are all able to limit the amount of blue light emitted by your Android smartphone or tablet. However, some of them offer more options and settings than others. We believe you will find one that is perfect for you. Try them out and keep the one you like best.
