Why everyone should wear bluelight blocking glasses at night

Ask yourself these 3 questions; 

Do you watch T.V. before you fall asleep at night?

Do you look at your phone or computer before you go to bed?

Do you play video games at night?

If you answered yes to any of these questions, than you need to keep reading. Did you know that TV, phones, and computer screens generate blue-wavelength light that stimulates sensors in your eyes to send signals to your brain’s internal clock?

What does that mean?  

In simple terms, our brain operates on a 24 hour clock where were awake for 16-18 hours and sleep 6-8 hours a night. During the day sunlight and white light contain a mixture of various wavelengths, each of which has a significant amount of blue light (10Trusted Source). Getting blue light, especially from the sun, during the day helps you stay attentive while increasing performance and mood. 

Yet, modern light bulbs and electronic devices, especially computer monitors, and any screens produce large amounts of blue light and may play havoc with your internal clock if you’re exposed to them during the evening.

When it gets dark, your pineal gland secretes the hormone melationin, which alerts your body to get tired and go to sleep.

Blue light wavelengths, whether from the sun or a a modern screen, is very effective at preventing melatonin production — thus reducing both the quantity and quality of your sleep.
