You might think wearing goggles with their blinking blue light would be annoying, but R.P.I. Grad student, Erin Ryan says, it's like a relaxing day at the beach.
And I can attest that they're comfy -- which is important because these goggles are geared to help you catch your zzz's.
The device is geared for seniors whose sleep has become disordered. They fall asleep too early, like 7 pm - and find themselves awake at 3 am.
Why this happens is three fold - aging, an inability for the body to effectively absorb light, and not spending enough time out of doors.
Taken together and you have a shortage of exposure to blue light during the day.
