Day And Night Feature

Feature Introduction​

The Day and Night feature in CareUEyes automatically adjusts screen brightness and color temperature based on the time of day, simulating natural light changes to provide a more comfortable visual experience, protect your eyes, improve sleep quality, and enhance work efficiency.

Feature Highlights​

1. Day Mode​

  • Provides brighter screen with higher color temperature (cool tones)
  • Enhances visibility and work efficiency
  • Ideal for use in daylight or well-lit environments

2. Night Mode​

  • Reduces screen brightness and blue light
  • Adjusts to lower color temperature (warm tones)
  • Alleviates eye strain
  • Prevents disruption of melatonin production for better sleep

3. Automatic Switching​

  • Switches modes automatically based on set times
  • Aligns with human biological clock
  • No manual adjustment needed

How It Works​

The Day and Night feature is controlled by three key factors:

1. Day and Night Color Temperature and Brightness​

Click the Day button to view daytime color temperature and brightness:

Practical Example​

Here's a specific working example:

Assume you set:

  • Day color temperature: 5000K
  • Night color temperature: 3700K
  • Sunrise time: 6:26
  • Sunset time: 17:54
  • Transition duration: 1 hour

The system will:

  1. Start transitioning at sunrise (6:26), increasing from 3700K to 5000K over 1 hour
  2. Begin transitioning before sunset (16:54), decreasing from 5000K to 3700K over 1 hour

You can view the current color temperature and brightness in real-time at the top-right corner:

Feature Toggle​

To disable the Day and Night feature, simply turn off the "Enable day and night feature" switch. When disabled, the system will maintain the same color temperature and brightness throughout the day:
