More eye protection solutions for CareUEyes

In addition to dimming the screen, there are more ways to protect our eyes, such as blue light filtering and regular breaks:

    • Blue light filter.

      Blue light is a high-energy short wave. Continuous exposure to blue light can cause eye fatigue, dryness, pain, and aggravate myopia. Blue light can directly reach the retina of the eye through the passage to the cornea and lens. Long-term exposure to excessive blue light can cause irreversible retinal damage, such as age-related macular degeneration.

      Turning on the blue light filter feature can reduce the damage of blue light to the eyes.

    • Take regular breaks 

      Working in front of a computer for a long time can easily cause eye fatigue, dry eyes, and other symptoms.

      It’s more beneficial for us to take a few minutes to break every once in a while, exercise our body, and see the distant scenery.
