Enabling this feature reduces the extra light on the screen, protects the user's eyes from harmful rays and illuminates the screen as per user's requirement. It makes the display on the screen easier on the eyes by loading off any excess bright light off the screen. Reduced pressure on the eyes is known to result in quality sleep and longer sleep hours.

Not just the light but even the colors on the screen are adjusted accordingly. It aids in protecting your eyes against excessive light and from hurting due to too much brightness on the screen. When you switch the brightness to day mode (which is also an available option) the entire screen light is made to fit daylight mode and gives maximum visibility to the viewer. To switch between day and night modes, simply access the light bulb that appears on the tool-bar drop down popup. If the modes are not automatically activated on each page just press Ctrl+Shift+F11 on each page. An added benefit of this extension is that it reduces battery consumption when switched on since brightness that is adjusted to real-time requirements will drain much less battery.
