This extension reduces the screen brightness level for both daytime and nighttime durations based on user-defined values. It is designed to reduce eyestrain while reading documents online. To enhance the usability the extension offers two different values for daytime and nighttime durations.

Note: It is possible to have no effect on daytime duration by setting the brightness level to 100%
Note: It is recommended to configure the start time for both daytime and nighttime. By default daytime starts at 08:00 and nighttime starts at 19:00.
