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.

      CareUEyesĀ  screen dimmer have a “night mode” setting that adjusts the brightness and contrast of the display to reduce the amount of blue light emitted by the screen. This blue light is known to disrupt sleep patterns and cause eye strain, so reducing its emission can help to reduce these effects.

      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.

    • Auto Dark

      Auto dark mode is becoming increasingly popular as people become more aware of the effects of prolonged screen use on eye health. It is a convenient feature that can help to improve the overall experience of using a computer or display device, and is a good choice for anyone who wants to reduce eye strain and improve the comfort of working with a screen.

    • Take regular breaks

      Taking regular breaks from screen use is another important strategy for reducing eye strain and improving the overall comfort of using a computer or other display device. The human eye was not designed to focus on a screen for extended periods of time, and prolonged screen use can lead to eye strain, headaches, and other symptoms.

      Experts recommend taking a break from screen use every 20 to 30 minutes, and looking away from the screen for a few minutes to give the eyes a chance to rest. This can include closing the eyes, looking out the window, or looking at something in the distance. During these breaks, it is also helpful to stretch, move around, and give the body a chance to rest.

      Taking regular breaks can help to reduce eye strain and improve the overall comfort of using a computer or other display device. It can also help to improve productivity, as taking a short break can help to refocus the mind and improve concentration. For these reasons, taking regular breaks is an important part of reducing the effects of prolonged screen use.
