Blue light and Why your monitor is bad for your sleep?

Eye Mastery (Day 2) – Blue light
and Why your monitor is bad for your sleep?

Before the beginning of this century, scientist knew that the retina contains only two types of photoreceptors which are responsible for the colors and pictures we see with our eyes.

Meet Ignacio Provencio. The neuroscientist who in 1998 found new photoreceptor called Melanopsin and for the first time proved that light is not only useful for our vision, but it’s critical for many biological processes.

Melanopsin activates when blue light enters our eye and it sends a signal to our brain that it’s day and our brains stops the secretion of our sleep hormone melatonin.

When we have melatonin in our bodies we feel sleepy and this is the reason why you can’t fall asleep when you sit in front of the computer at night.

Monitors and all electronic devices emit blue light.

This blue light enters our eyes and melanopsin activates.

Our brain receives a signal to stop the secretion of our sleep hormone melanopsin.

We can’t fall asleep, our circadian rhythm changes and our brain think that it’s day.
