LightBulb

LightBulb is a very light software that will help you to reduce eye fatigue when staring at your PC screen during the afternoon and evening hours. The program will adjust your monitor's color temperature progressively as the day goes on, going from cooler colors in the morning to much warmer colors in the evening.

It is very easy to set up and use

Getting started with LightBulb is very easy. All you have to do is unzip the entire contents of the compressed file into a new folder and double-click on the executable. And that's it. After this first step, you will have to accept the terms of use, which are also listed on the author's website. Finally, you can configure some aspects of the app to customize it to your liking.

Find a range of configuration options

Although it is not strictly necessary, it is highly recommended that you look at the configuration options. From this tab, you can adjust the color temperature for day and night and set the value of your choice. You can also adjust the day and night screen brightness and even choose how long you want this transition to last. The longer the transition, the more gradual the change will be.

Create your own exceptions

Another interesting feature in LightBulb allows you to create exceptions whitelist. Any program you add to this list won't be affected by the change in color temperature. This way, if you don't want your video player or a specific video game to be affected, you just have to add them to the list. In any case, you can also set keyboard shortcuts to turn the app on and off.

Improve your health and let your eyes rest

This is very common on mobile devices but, for some reason, is often overlooked on the PC. And many people spend more than eight hours a day in front of a monitor.
