Windows 10 allows you to enable Night Light mode (previously known as Blue Light) to reduce eye strain. When enabled, it makes the screen color gamma more comfortable for your eyes at night by reducing blue light. Colors become more warm and the backlight will be dimmed, so eye fatigue will be less. Some users are faced with a strange issue where the Night Light options are grayed out in the Settings app. Here is a quick workaround to resolve this issue.
As you may already know, the latest Insider Preview builds of Windows 10 include features that the next major feature update to Windows 10, known as 'Redstone 2' will have. While there is no information yet on what exactly will be included in the final version of Redstone 2, a couple of new features recently discovered can give us an idea.
