Help with eye fatigue on your Galaxy phone

Woman looking at phone at night

Is your Galaxy phone's bright white screen hurting your eyes? If so, just turn on the Blue light filter or Eye Comfort Shield to remove blue light from your phone's display. This can help prevent eye strain, especially when you use your phone at night or in low-light settings.

Enable Eye comfort shield

The new Eye comfort shield option is available on One UI 3.1 devices, including the new Galaxy S21 series. You can turn this on to limit your screen’s blue light. It's similar to the regular Blue light filter except a special algorithm will adjust your screen's color depending on external factors, such as how bright it is outside.

Using two fingers, swipe down from the top of the screen to open the Quick settings panel. Navigate to and tap the Eye comfort shield icon. If the Eye comfort shield icon doesn’t appear in your Quick settings panel, you can add it. The icon will glow blue when it's enabled, and your screen's color will have a slightly yellow tint that will change over time.

Touch and hold the Eye comfort shield icon to adjust the settings. You can select Adaptive to change the screen’s colors based on the time of day, or Custom to choose a schedule and color temperature that is right for you.

Here are the options for Custom:

  • Set schedule: Choose from Always on to keep Eye Comfort Shield enabled at all times, Sunset to sunrise, or custom. With custom, you can choose the exact time you’d like Eye Comfort Shield to turn on and off.

  • Color temperature: Adjust the slider to change the screen’s color tone.

Enable the Blue light filter

When your eyes are feeling a little sore from staring at your phone, turn on the Blue light filter to get some relief. You'll be able to use the Blue light filter option on devices running One UI 2.5, One UI 3, or earlier software versions.

Using two fingers, swipe down from the top of the screen to open the Quick settings panel. Navigate to and tap the Blue light filter icon to turn it on. If you don’t see the Blue light filter icon in your Quick settings panel, you can add it. The icon will glow blue when it's enabled, and your screen's color will have a slightly yellow tint.

To adjust the Blue light filter's settings, touch and hold the icon. From here, you can adjust the filter's opacity by moving the slider. You can also tap Turn on as scheduled if you'd prefer to have the filter turn on and off at a specific time.

  • Custom schedule: Allows specific times to be set to enable and disable the filter.
