One of the main mistakes when using a smartphone is to adjust the brightness of the screen. Usually, it is performed by beginners who have purchased a new smartphone and have not yet reached the screen settings. By the way, this is one of the most important functions that you always need to control: regardless of whether the IPS or OLED screen is installed in your smartphone, you can begin to experience discomfort. Whether your eyes get tired or not depends not only on the type of screen but also on the level of brightness that you set. We tell you what you need to set up on your smartphone to save your own eyes.
Which screen brightness is best for the eyes
Setting the brightness of the screen too high or low is harmful: for example, you have turned on the battery saver and are trying to extend the life of the smartphone. The picture is dull, which is why the eyes strain to examine the image or read the text. The longer the smartphone is in this mode, the more time your eyes will be in a tense state: at this time the muscles responsible for pupil dilation get tired.
A similar problem with high brightness: there are no problems with the visibility of the image, but you have to squint, straining your eyes again, as a result of which they get tired. What to do in such a situation? Adjust the brightness of the display manually depending on the lighting or take advantage of the auto-brightness, which does this with the help of sensors. In addition, automatic brightness adjustment saves battery power: the smartphone changes the backlight level of the screen only when necessary.
Adjust the screen brightness on your phone
On the Web, you can find dozens of tips for adjusting the brightness of the phone: most of them boil down to the fact that you need to set it at 30, 40 or 50% – they say, it is more convenient for the eyes, does not drain the battery so much and on the screen, everything is quite distinguishable even in bright sun. This is not so: each smartphone has its brightness indicators and displays design features. For example, AMOLED screens a priori seem brighter due to saturated colours.
And also take into account the fact that each person has his threshold of comfort. As a result, it may seem that even 30% of the brightness is too much on a cloudy day or while reading, and 50% is not enough. Sometimes even the maximum brightness of the display can be comfortable, for example, while washing dishes and watching videos on a smartphone that stands one and a half meters from you. Pay attention to whether the image does not cut the eyes and does not make you strain them unnecessarily. If everything is good, then the brightness does not need to be changed.
Screen brightness on Android
Smartphone manufacturers are worried about their users and are trying to provide them with comfortable use of the device. Therefore, both on the iPhone and in smartphones on Android, you can find additional functions of screen brightness.
- Adaptive brightness changes the brightness of the value depending on the environmental conditions. This is the auto-brightness of the display.
- Blue Light Filter: Very convenient when using your phone in the dark. It reduces the shades of blue and white so that the image becomes not so bright and does not press on the eyes.
- Dimming mode: thanks to it, the design of the interface changes from light to dark on a schedule or manually, and also applies to the wallpaper on the screen, making it less bright.
- Take a look at the “Screen Mode” settings, if any: there you can adjust the colour reproduction of the screen by choosing more comfortable shades.
Brightness doesn’t work on your phone
For some reason, sometimes it is not possible to change the brightness of the smartphone, as a result of which it is not possible to adjust the phone for comfortable work. What is it and why is it happening?
- You used too thick or too darkened protective glass. For example, matte, because of which even at 100% brightness it seems that something is wrong with the smartphone and nothing is visible on the screen.
- Your smartphone has warmed up: as a result of throttling, the processor begins to lose the load and reduces performance. In particular, the brightness of the screen decreases, although it is set to 100%.
- Auto-brightness does not work correctly: it seems that you need to calibrate it. How to do this – is told in our article.
As you can imagine, there are no perfect screen brightness settings. It is best to set the optimal screen settings, with which it is much more comfortable to use the screen. In addition, you need to use the built-in functions of the smartphone – they will be useful for the eyes.
