How to Reduce Blue Light Radiation

Blue light is a part of the visible light that can damage the retina if exposed for a long time. The scientist also found that blue light radiation from the smartphone and the computer screen can screw up the sleep patterns.

While technology products are inevitable for daily use, the only thing that can we do is reduce the blue light on the monitor screen. But how?

The primary color that every day we see is based on a combination of red, green, and blue, which known as RGB color. As it names, the blue light comes from a blue color. The intensity of the color can be adjusted after the following options.

Twilight is my favorite app to trim blue light at the lowest possible point. It allows you to customize the color temperature, intensity, and screen brightness. It comes with a scheduling option that automatically adjusts the exposure of light depending on the time location.

For example, during the day, the color temperature is set to be normal, but when the night is coming, it will increase red light and reduce blue light to help you sleep at the right time.

Once it activated, the color slowly becomes warm, and the blue color dramatically reduced. Twilight was also offering a Pro version with more features, but for me, the basic option is good enough.

Night Filter can monitor your activity related the eyes health. It has a warning notification if you have been staring at the phone for a long time without a blue light filter. It also tracks eye habits with detailed daily health report. The app was more straightforward than Twilight and Blue Light Filter but featuring a reminder for users to do some exercises after using the phone.

The app claimed that their screen settings could save the battery up to 15 percent of daily use. It sounds reasonable because of screen dim is naturally throttled down the brightness, and eventually, reduce power consumption.

Note: Activating blue light filter would affect the actual color of the screen. Turn off the app when you intend to record a video, take a photo, or capture a screenshot.

Monitor quality is getting better and better. Current technology brings vivid color and customizable filter for the monitor. But, the most important things is the ability to reduce the blue light. Luckily, major screen monitor manufacturers understand the demand and introducing eye-friendly display in the past couple of years.

If you planned to buy a new monitor, consider the blue light reduction feature. The hardware-based filter is commonly way better than software filtering as it designed to ensure the light configuration matched with the monitor system.

In addition, flicker-free monitor surprisingly decreases the fatigue of eyes despite you have been staring at the monitor for like 8 hours a day. Unfortunately, this technology only available on BenQ’s monitor. The patent remains for this company and no other monitor brands on the market offering flicker-free display. The BenQ Eye Care monitor widely exists on several applications, such as gaming, home, office, and professionals.

One aggressive approach is embedding blue light filter onto the phone or computer screen. It set the color temperature, brightness, and screen dim with fixed level, no matter what actual conditions have been. This option might be right for people that were rarely using color-sensitive software and parents that won’t screen display hurt their children eyes.

I was discovering the price of the blue light screen protector costs you between $10 to $40 (USD). Again, never install this kind of screen protector if you were often watching videos, edit some photos, and other color-sensitive activity.

The anti-blue light glasses are a healthy-stylish choice, especially for people that usually wearing glasses for almost the entire day. There are numbers of glasses maker creating special glasses for blocking the blue light from the computer screen.

Although you were installing apps to filtering the screen, adding a blue light filter screen protector, or purchasing a new monitor that helps you reduce the strain of eyes, it’s important to take a break during your heavy working.
