Are you looking for a screen dimmer?

Then you’re in the right place.

Because today I’m going to show you the most popular screen dimmer solutions.

Why do you need a screen dimmer?

    • Bright screens cause  eye irritation and dry eyes
    • Bright screens cause  eyes fatigue
    • Bright screens cause trouble sleeping
    • Adjusting screen brightness to be suitable is very important for the eyes.
      The screen dimmer helps adjust the screen brightness,  reduce eye strain, prevent eye diseases, and improve sleep.

Three ways to reduce screen brightness

    1. Use the brightness adjustment button of the monitor, display, or screen
    2. Use the built-in brightness adjustment of windows (System->Display)
    3. Use the laptop keyboard shortcut Fn+F11 or Fn+ F12
😒But the above three methods to reduce screen brightness
are cumbersome and usually useless. People have to look for other solutions.

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.
