Sleep issues are on the rise
for kids who use devices.
Make sure your child is protected at home and in school.
You worry about how all that screen time is affecting your child. That worry is well placed. Blue light from everyday devices — tablets and phones — may cause eyestrain, headaches and even sleep disorders.
Why are children at risk?
No natural protection
The lens in a human eye doesn’t filter blue light until around age 40.
Shorter arms, hold devices closer
The closer the device is to the eyes, the greater the exposure.
Larger pupils permit more light to enter the eye.
Average daily media use
Teens (13+) 9 hrs a day
Tweens (8-12) 6 hrs a day

Blue light may cause sleep loss - and more
Blue light suppresses melatonin
Melatonin is the body’s natural sleep hormone.
It takes longer to fall asleep
Blue light, especially before bed, disrupts the body’s internal clock.
Quality of sleep suffers
Restlessness adds to sleep deficit.
Chronic sleep loss may have health consequences including weakened immunity, ADHD, type 2 diabetes, obesity, heart disease and cancer.
Blue Light FAQ
What is Blue Light?
Unlike UV, which is filtered by the cornea and crystalline lens, blue light is the highest energy light that actually makes it to the back of the eye. Our eyes have no natural protection in our younger years.
Where does blue light come from?
You encounter blue light in everyday activities. Fluorescent lighting, electronic screens (phones, tablets, computers, TVs, etc.), and the sun emit damaging high-energy blue light.
Is there good blue light?
Not at night. According to Harvard researchers, even dim light can interfere with a person’s circadian rhythm and melatonin secretion. “A level of brightness of about twice that of a night light has an effect.”
How does blue light affect us?

Sunscreen for eyes
"Eyewear will be chosen and recommended based on the percentage of blue filtration, the same way sunscreen is based on SPF values. Seventy million Americans suffer from sleep disorders and deficiency. This is likely to get worse over the next decade. There will be more studies confirming the relationship between evening blue light exposure and disruption of the sleep-wake cycle, and increasing demand for eyewear filtering blue light in the upper end (480nm)."
