Blue Light: What Role Does it Play?

Blue light comes from various sources, including your device, but the largest source of blue light comes from the sun. Because of this, your body uses blue light to control your circadian rhythm and help your body differentiate day and night.

Blue light was originally thought to be the cause of digital eye strain. However, recent studies have suggested that blue light correlates with sleep deprivation more than digital eye strain. According to research, using a digital device before going to bed can make it harder to fall asleep as your brain interprets the blue light signals as daytime. Experts recommend to stop using devices two hours before bedtime.
