NASA sleeping mask
NASA technologies were used in this night mask to regulate your sleep. This mask uses blue and red lights to combat insomnia and other problems with sleep. It blocks all ambient lights and uses 2 colors to create a comfortable atmosphere for your eyes, giving the illusion of sunset or sunrise to make you easily fall asleep or wake up. So if you’re a very sensitive person and it’s easy to disturb your sleep, you can use such a mask, especially if you’re going to travel somewhere and there’s a big time difference.
