In 2019, California passed the State Blue Light Resolution SCR-73, declaring October 10 as Blue Light Awareness Day. Screen time now exceeds 13 hours per day, which means we are exposed to higher levels of blue light than ever before. This holiday is a good reminder for us to learn about blue light and the ways we can protect ourselves and our families.
What is blue light?
To understand the importance of Blue Light Awareness Day, it’s helpful to know exactly what blue light is. Blue light is a high-energy visible light that can be seen by human eyes.
While the sun is our largest source of blue light, digital devices such as laptops, computer monitors, and smartphones also give off blue light. Blue light from devices is especially concerning because of how close the screens our to our eyes and the amount of time we spend on our devices nearly every day.
Why is blue light a concern?
According to a recent survey, 94% of eye doctors are concerned about rising screen time and blue light, and for good reason. Symptoms most cited by eye care professionals as a result of excessive blue light exposure from digital devices include dry eyes, blurred vision, headaches and even reduced productivity.
Research at the University of Texas Southwestern Medical Center found that blue light also suppresses the release of melatonin, the sleep hormone. Because of this, late-night device use may result in sleep disruption. As we know, lack of sleep can also lead to reduced alertness the next day and impacted mood and behavior.
Additionally, according to the AOA foundation, children may be at greater risk of blue light exposure because their eyes don’t have the same blue light-filtering ability as adults’ eyes. Children also position digital devices closer to their eyes, increasing the intensity of their blue light exposure.

Blue Light Awareness Day reminds us of the importance of protecting ourselves against blue light from digital screens.
