Are you searching for a blue light filter for your computer screen? You might be aware of some of the risks associated with blue light.
Blue light emitted by computer screens can significantly affect both eye health and sleep quality. Prolonged exposure to blue light can lead to digital eye strain, resulting in symptoms such as dryness, irritation, and difficulty focusing. Moreover, blue light interferes with the production of melatonin, the hormone responsible for regulating sleep. This disruption can make it harder to fall asleep and maintain a healthy sleep cycle, potentially leading to fatigue and decreased overall well-being.
What is a blue light filter for computer screen?
Software-based blue light filters work by adjusting the color temperature of your computer screen to reduce the amount of blue light emitted. These filters typically use algorithms to shift the display’s colors towards warmer tones, such as amber or orange, especially during evening hours. This shift not only decreases blue light exposure but also enhances visual comfort, making it easier on the eyes. Many of these filters can be customized, allowing users to set specific times for activation and adjust the intensity according to their preferences, ultimately promoting better eye health and improved sleep quality.
Hardware-based blue light filters work by physically blocking or absorbing blue light before it reaches your eyes. These filters are typically applied as screen protectors or overlays that are placed directly on the display. They use specialized materials designed to filter out blue light wavelengths while maintaining the clarity and brightness of the screen.

Adjustable blue light blocking rate
CareUEyes filters blue light by adjusting the color temperature, because the higher the color temperature of the computer screen, the more blue light is emitted, and vice versa.
Therefore, with CareUEyes you can adjust the blue light blocking rate arbitrarily (but the physical filter device cannot adjust it).
Why do I emphasize this point? Because it is very useful.
In the daytime, the color temperature should match the external light, and 5000K-5500k is recommended. This can eliminate the damage to the eyes caused by the accumulation of blue light energy, and at the same time, there is an appropriate amount of blue light to keep people awake during the day and be more energetic to deal with this day’s things.
At night, the color temperature should be set to match the light in your room, and a low temperature of 3700K-5000K is recommended. At this time, we don’t need blue light to suppress melatonin secretion, and the body does not need to be in a state of excitement. The beneficial blue light during the day has been transformed into harmful blue light at this time.
On the contrary, we need to secrete melatonin to a certain concentration, which will help us fall asleep and ensure good sleep quality.
Through the comparison of blue light intake at different time periods during the day and night, the changes in the concentration of melatonin can be better adjusted, and the quality of night sleep can be further improved.
As long as you turn on the sunrise and sunset functions, CareUEyes can automatically switch between the two modes for you according to the time of sunrise and sunset.
Eight preset modes allow you to easily and quickly filter blue light.
CareUEyes provides eight preset modes, you can switch between pause, health, game, movie, office, editing, movie, reading, and customization at will.
Each of these options provides a slightly different experience for the user and changes the brightness of the display to suit a specific task or activity.
If you are not satisfied with the preset mode, you can also modify the preset mode.
Adjustable screen brightness provides further protection for your eyes.
CareUEyes has the function of adjusting the brightness of the screen to protect the eyes more comprehensively.
For many monitors, adjusting the screen brightness is very troublesome. Using CareUEyes can easily adjust the screen brightness. Not only can you adjust the brightness by dragging the progress bar on the main interface, but you can also use the hotkey to adjust it more conveniently.
Timed reminders for breaks are essential for eye protection
Regular rest is an effective way to prevent eye fatigue. The famous 20-20-20 rule: Every 20 minutes, look at an object 20 feet away for 20 seconds.
If you are busy with work, you may not have time to stop and rest frequently, because this may reduce your work efficiency.
CareUEyes reminds you to rest for 5 minutes every hour by default, but the interval and duration of rest can be customized.
This is not a simple timer, it can intelligently detect your use of the computer.
For example, if you leave the computer midway, the timer will automatically pause. After a certain period of time, the timer will restart when you return to the computer.
Many people, because of their busy work or minors with low self-discipline, know that they cannot leave the computer to take a break when it is time for a break.
For the above-mentioned people, you can use CareUEyes’ forced rest mode and turn on the password protection function, so that you will not miss the rest.
CareUEyes is a product you will love after using it.
