Lenovo Vantage Eye Care Mode

Understanding the potential dangers of blue light, Lenovo Vantage developed an “Eye Care Mode” tool that reduces the blue light emitted from LEDs widely utilized in today’s PC monitors.

How to use Eye Care Mode in Lenovo Vantage:

  1. Search “Lenovo Vantage” using your Windows OS search function (in the beginning menu or taskbar, lower-left corner of your computer).
  2. Click “Lenovo Vantage” 
  3. Click the “Hardware Settings” button on the most page, then select “Audio/Visual.”
  4. In the “Eye Care Mode” section, when a user activates the “Eye Care Mode” toggle, blue light emission will be reduced to a more manageable level, and therefore the slide bar can’t be moved. If the user turns off the “Eye Care Mode” toggle, blue light emission will return to the user set’s last value.
  5. The user will be ready to slide the bar to regulate the blue light emission level when the “Eye Care Mode” toggle is turned off. Sliding the bar to the left leads to a hotter screen color and the proper a colder screen color.
