Blue light has the shortest wavelengths and highest energy, which can keep you from falling asleep peacefully and cause eye strain. A 2016 American Eye-Q® survey revealed that the average American spends seven or more hours per day looking at their screens. This overexposure to blue light can also result in blurred vision, headaches, and neck and shoulder pain.
For those who use multiple monitors all day, scroll cell phones and tablets, play video games or watch TV (i.e., everyone), try using the blue light filter or night light in the evenings on your devices. For example, Apple now offers a feature called Night Shift, which shifts the colors in your display to the warmer end of the spectrum, and which you can set to automatically turn on at a certain time. There are options for Android devices as well. Blue light filters have been proven to decrease eye irritation and help some people fall asleep easier. Search for blue light filter or night light on your device and try it out.
Not all blue light is bad, though. You do want to be alert and energetic sometimes! Another option to consider are glasses with special lenses that filter blue light.
Here’s to less eye drops and more zzzs!
