Ever worry about how your computer habits can affect your life? You should, because blue light has been shown to disrupt your sleep cycles, delaying the amount of time it takes for you to fall asleep. Please check out Ontario Association of Optometrist's video Sleepless | Are Screens Keeping You Awake? to learn more. There are a few ways to reduce the amount of blue light exposure from using your devices. You can purchase glasses with an anti-reflective coating that filters the blue light, reducing the amount that reaches your eyes.
In addition to those blue light AR-coating glasses, you can do a few tricks on your PC/Mac, Android, or iOS devices that reduce the emission of blue light. Generally, these will remove blue light from showing on your screen, which leads to softer and yellower light that is easier on your eyes. Below are step-by-step instructions on how to set up a blue light filter for your device:
The best, and easiest solution is a program that you can install called f.lux . This program is great because it is so easy to set up. Based on your location that you enter, f.lux will automatically pick up on when the sun sets and rises to turn on or off the blue light filter.
- Download f.lux for PC or for MacOS
- Install and follow the prompts needed to complete set up
It's seriously that simple. There are settings where you can adjust the colour of the filters but I don't recommend playing around with it. Also, you can disable the filter for one hour when you need to do colour-sensitive work, such as graphics design, or watching videos. You can access all of this in in the System Tray on Windows:
