In this age of computer + Internet, many of our jobs are computer dependent, even require us to sit in front of computer for a long time. As we all know, computer does a lot of harm to our health in many ways. One of them is that the large amount of harmful blue light emitted from display can damage our retina, thus leading to maculopathy and cataract, causing asthenopia (eye strain), and leading to poor sleep quality and even insomnia.

SunsetScreen is an excellent and pretty practical eye protection software on computer that was specially made for people who often uses computer, which can automatically adjust the brightness and color temperature of screen by setting the sunrise time and sunset time. It has a powerful anti-blue-light function, can effectively reduce the harm of blue light from computer to the human eye, and protect our eyes. In addition, it comes with small file size (less than 1 MB), compact interface, and is free and portable.

SunsetScreen can achieve the same effect as f.lux and Windows 10’s built-in night mode. But the difference is that it is also able to help you automatically adjust the brightness of your computer screen. However, it also has a disadvantage of being not able to automatically determine the time of sunrise and sunset based on your location. Instead, you have to manually adjust the time you want to go into the night mode.

SunsetScreen runs automatically in the background, and automatically adjusts the brightness and color temperature of the display for you during the time period you specify (mainly at night). Its main function is makes the light from the monitor do not hurt your eye, makes sure that you can work at night without feeling uncomfortable due to too much harmful blue light, so as to help you sleep better.

There is no doubt that for any people who have to sit in front of a computer for a long time, it is very necessary to install such an eye protection software on the computer. Whether you’re an early riser or a night owl (late sleeper), SunsetScreen gives you complete control over your sleep cycle. For nightbirds, you might want to set the sunrise time to around 9 o’clock A.M.; or if you get up very early every day, you may want to set it to 4 o’clock before dawn.
