flashing lights to help you sleep when in Vegas.

From American public media this is marketplace tech.

I'm Lily Dramale. It's my third day at CES and amid the demos, launches, meetings, greetings, keynotes, and all the walking.

There's one thing that's been on my mind, sleep.

So I stopped by the National Sleep Foundation's booth to meet some other folks thinking about sleep.

I spoke with B. Tranlo, co-founder and CEO of Lumos Tech.

Her company makes what looks like a regular sleep mask, but there are LED lights

embedded in the mask which is designed to help recalibrate a user's sleep

schedule. I am intrigued so I ask her how the eye mask works.

You're going to tell us what is your current bedtime

and then when you want to move your bedtime too.

So if you're a night out that always go to bed at 3 a.m. but you want to

become an early person then you would just tell us I'm currently going to bed at 3 a.m.

But I want to go to bed at 11 a.m. be able to fall asleep. You're saying that's possible I can

go from being a night out to an early bird? Yes. I'll believe it when I see it. Oh yeah.

It's quite a proposition I like like it. Yeah, so by adjusting your circadian clock,

you're able to move your sleep schedule.

And then once you program in the app,

it's going to determine what is the best sleep program for you.

Then it's going to send it to the mask.

So what you do as a user is you will put on the mask

before you go to bed at your normal bedtime.
