Do you often suffer from eyestrain or eye-fatigue? Do you have trouble sleeping at night after you shut off your computer? You may be exposed to too much blue light through your computer screen. Some blue light is fine during the day to help keep you alert, but being exposed to too much of it can cause issues.
To help decrease the amount of blue light you see, try enabling your computer to emit warmer colors through Windows’ Night light or Mac’s Night Shift settings.
Windows 10 (Night light)
- Click the Windows Start Menu then scroll down the list of apps and click Settings.
- Click System.
- In Display, find Night light underneath Change brightness and toggle the switch from Off to On.
- To edit the color temperature that your screen displays or what time the feature turns on for, click Night light settings.
Mac OS (Night Shift)
- Click the Apple Menu then click System Preferences.
- Click Displays then click Night Shift.
- If you would like to set up Night Shift to go off at a certain time, click the drop-down menu next to Schedule: and choose if you would like to enable Night Shift from sunset to sunrise or between a custom time frame. Note that if you would like Night light to turn on from sunset to sunrise, you will have to turn on location services on your Mac to determine when it’s nighttime in your geographic area.
If you would like to turn on Night Shift immediately, click the checkbox next to Manual: Turn On Until Sunrise. Night Shift will be enabled until the next sunrise.
If you want to adjust the color temperature that your screen displays when Night Shift is on, slide the scale to your preferences next to Color Temperature.
Bonus Tip: This feature is also available on your smartphone. Search for Nightshift or Nightmode and your phone for instructions.
