The Health Costs of Screen Time

According to a recent study, children under 8 years old are now spending more than 2 hours per day in front of screens and the blue light they emit. In an increasingly digital world, it’s hard to see screen time decreasing as our children age. That’s why it’s critical to understand the risks blue light poses to our kids and how to protect their developing eyes. In recent years, experts have linked blue light exposure in children to blurred vision, disruption in sleep patterns, eye fatigue, neck and shoulder pain, and more.


Undeveloped Eyes Need Maximum Protection from Blue Light. While some experts downplay the effects of blue light on adults, the data regarding the impact of blue light on developing eyes is conclusive. Children are more likely to be negatively impacted by blue light because kids have larger pupils than adults and haven’t yet developed the protective pigment that shields mature eyes. Recent studies have also shown that melatonin suppression in prepubescent children far outpaces that of older children and young adults, a leading indicator of significant disruption in sleep patterns.
