What is Blue Light

Blue light is found in the visible light spectrum, with a wavelength of 400 to 490 nanometers. Often referred to as a high-energy visible light (HEV), natural blue light is located in sunlight.  It helps regulate circadian rhythms, telling our bodies when to wake up and go to sleep.  Natural blue light in moderation can be beneficial.  

Artificial blue light is emitted from tech devices such as laptop, smartphones, tablets and TVs.  Many studies done on blue light show that exposure to artificial blue light from digital devices can cause sleep problems, such as insomnia. Blue light can also affect eyesight, including blurred vision, eyestrain, pain and eye fatigue.

Exposure to artificial blue light is starting at younger and younger ages.  Our kids are growing up looking at screens through their day, whether at school, for homework, videos, video games, social media... 

Young eyes have not developed as much natural protection to artificial blue light from screens as adult eyes.  The long hours kids spend in front of digital devices puts kids eyes and health at greater risk today than ever before.
