Take care of your eyesight by adjusting the brightness of your screen for free with flux

When it comes to being in front of the computer screen for long hours, there is an element that we often overlook, but it is very important for our health, such as the brightness of the screen and blue light. Intense and prolonged use of it can be harmful to our eyes, causing the famous visual fatigue. This is something that can happen if we always maintain the same level of brightness, regardless of the lighting conditions. To help us with this work, we can use a tool like f.lux .

The brightness and temperature of our screen is a very important issue that we cannot ignore when we sit in front of the computer. The level of brightness during the day, in which we find greater clarity, should be higher. Instead, at night, the brightness should be much lower. In this way, we adapt the brightness to the light situation by reducing blue light, something that greatly favors the health of our eyes, since it prevents the appearance of visual fatigue . For all users who are concerned about the damage that blue light can cause to their eyes when used in low light environments, a program such as f.lux is available to them, which we will talk about below.

Adjust brightness and temperature automatically with f.lux

F.lux is a software developed so that we can adapt the color and brightness of our computer screen depending on the hours of the day. The application takes care of creating a personalized lighting schedule for every day. To do this, the program is configured based on our location thanks to Google Maps, and based on this it adjusts the parameters of our monitor. It also allows us to preview the result before applying any changes, so that we can check if the brightness setting is correct.

In this way, f.lux allows us to adjust the tones of our screen, adapting to the light conditions of each hour of the day to reduce the blue color and protect our eyes from these damages. Thus, we will have more muted and yellowish tones at night and more vivid and whitish tones during the day. In addition, it allows us to adjust the equipment in the case that we have an intelligent lighting system so that it can adapt to the same tones and brightness of the screen. It is also possible to configure it so that it is not activated by a certain application that requires special brightness conditions.

Use their geolocation system

Once we run the application for the first time, a geolocation screen will appear. In it we must enter our location so that the program can locate us and establish the sunrise and sunset times, based on which we can adjust the tone and brightness of our screen.

Subsequently, its main menu will appear where we can configure various options. For example, in the lower left part we must select the usual time we wake up. In the central part the solar time appears, as well as the time that we woke up and the time since it woke up. Just above we find a color configuration bar that the application has established for the time we meet. We can slide it to adjust it to another tonality if we think it is necessary.

Make different color adjustments

If we click on the three horizontal bars that we find in the upper left part, several tabs are opened where we can make adjustments to the colors of the day and night together, smart lighting options and change the current color to different tones. It also includes additional effects and colors that we can set as “Movie mode”, “Dark mode”, “Soft white”, “Blue sky”, among others.

Another interesting function that we are going to find is “Disable”. This option can be used automatically for applications where color quality is essential and we do not need to adjust it. We can also disable the program for an hour, until dawn, in applications that use the full screen. We can also deactivate some specific programs that we are using at that moment so that they do not suffer changes. For example, if we are using Word and we do not want to change the brightness, we can deactivate it from this option.

Color recommendation, with default profiles.

Finally, in the upper right we find a button to make custom color patterns.  If we click on it, a drop-down menu appears where we can choose different predetermined color combinations . For example, we will find a way to reduce visual fatigue, the classic f.lux mode, a special mode for working late, a mode that offers greater color fidelity among others. If we select one or the other, we will see how the menu sliding bar changes adjusting to each mode.
