控制你的浏览器的全局屏幕亮度，以使用不支持本地黑暗主题的网站

This extension reduces the screen brightness level for both daytime and nighttime periods 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 duration. 

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."
