Blue Light Blocking Glasses


“Throughout evolution, brightness meant that it was daytime and that we should be awake and get stuff done, while darkness meant that it was time to sleep and recover.” -Kris Gunnars

The Problem:

Modern light bulbs and electronic devices (especially computer monitors), also produce large amounts of blue light and “trick” our brains into thinking that it is daytime.


When it gets dark in the evening, a part of the brain called the pineal gland secretes the hormone melatonin, which signals to our bodies and brains that it is time to get tired and go to sleep.

Blue light, whether from the sun or a laptop, is very effective at inhibiting melatonin production.

This means that our bodies don’t get the proper signal that it’s time to go to sleep, reducing both the quantity and quality of our sleep.

Studies have linked melatonin suppression in the evening to various health problems, including metabolic syndrome, obesity and cancer,  as well as mental disorders like depression

The Solution(s):

(1) Don’t use any blue light devices after a set time typically a few hours before bed (TVs, Smartphones, lights, etc). Stick to candle light or non blue light producing devices.

(2)  Download software for your computer/mobile devices:

(3) My older TV and newer ones as well don’t have apps that you can just download. So ultimately the best solution is to wear blue light blocking glasses for a few hours before you go to bed. Kendra and I have been discussing getting some for a while now but the other day a friend of hers reminded us about them. Me and Kendra have some on order from Amazon. I will write more about the once I have used the for a few weeks.
