Did you know your cellphone is emitting a potentially harmful blue light? 

Entrepreneur Gigi Mortimer noticed her son, Nick, couldn’t get to sleep after being on his phone.

“I started researching about blue light, it made total sense, it said blue light triggers the brain to thinking it's daytime,” the concerned mom told Inside Edition. 

UC Irvine ophthalmologist Dr. Andrew Smith agrees. The blue light can decrease melatonin, which is the hormone that regulates the sleep-wake cycle. 

“The ultimate source of blue light in our life is the sun, so if you're out in the day, you're awake ... then it goes down at night and you go to sleep," Smith said.

"But if you're getting exposed to blue light that blue light is stimulating the brain to stay awake," he added.

Mortimer was determined to help her son.

“I had to do something to protect my kids’ eyes and their sleep. I was on a mission," she said.

So Mortimer worked with the UC Irvine doctors and came up with Eye Just, a clear screen protector that claims to block the potentially harmful blue light coming from your phone. It’s made of a UV blocker similar to what’s in sunglasses.

“People should be very concerned about the amount of time their children are staring at their screens,” Mortimer said. 

When you use the protector in conjunction with your screen brightness set low, the blue light is reduced by 85 percent, helping you get to sleep.
