Blue Light Blocking Glasses: How they Improve your Sleep


Sleep is a beautiful thing, wouldn’t you agree?


Insomnia: A thief that robs from me every night

In terms of our physical and mental health, it has many benefits that we need to live a healthy daily life. However, as our lives get increasingly busy, we tend to find ourselves spending longer evenings working in the office or studying away in the library. Nowadays, our sleep is always the first to go when we have more pressing life matters at hand. Unfortunately, these habits can affect our sleep patterns in a very harmful way. There are several articles proving that sleep is highly important for your health. It’s good for your immune system and helps to prevent high blood pressure, heart disease and stroke.

Sleep plays a vital role in good health and well-being throughout your life. Getting enough quality sleep at the right times can help protect your mental health, physical health, quality of life, and safety. – National Heart, Blood and Lung Institute

Why is blue light dangerous?

When we spend long evening hours looking at our mobile phones, tablets or computer screens, our bodies are absorbing large amounts of what is called “blue light”. Blue light is the bright, artificial light that is produced by LED screens, which are now included in most of our modern day technological devices. Although it can increase our attention span during the day, blue light absorbed during evening hours can actually have a very negative effect on our body’s natural clock aka our “circadian rhythm”.


When it gets dark outside at the end of the day, our brain begins to produce a natural chemical called melatonin which signals to our body that it’s time to go to sleep soon. However, studies have shown that the short light wavelength that LED screens emit actually inhibit the natural production of melatonin, which is why we may experience insomnia like symptoms after working late nights. Insomnia is a wide spread problem among people today and can be harmless for the brain.


Now, I know what you’re thinking, “Well, I want to keep working during the evening, and so am I doomed to go on living this sleepless life forever?” Well, I am happy to let you know that there is a solution for all you workaholics out there (they do exist)!

Glasses that block blue light

In fact, there is an easy and also stylish way to combat these nasty blue LED lights. They are called blue blocking glasses and they are a great natural sleep aid for people who are suffering from sleep deprivation or normally have sleeping trouble after working at night. As an idea that originally came from NASA, the amber lenses are specifically designed to block blue LED light and harmful UV rays that are disrupting our natural melatonin intake. Basically, the amber lenses work by filtering out the blue light portion from the visible colour spectrum when you’re using your devices at night. Therefore, all you have to do is wear them while you’re working at night, and you will soon find yourself in dreamland bliss! Not to mention, you can always wear these glasses during the day as well for continued protection.

In fact, Gunnar produces glasses that are suited for both blue light blocking and UV protection. We have written about them before and you can read all about Gunnar glasses here. Be sure to head over to the SmartBuyGlasses website to pick up a pair. Sweet dreams smart buyers!

Clean Sleeping

The topic regarding sleep is highly important and  Gwyneth Paltrow is now introducing the idea of “clean sleeping”. According to the actress, clean sleeping is simply trying to get good, quality sleep on a regular basis. Clean sleeping is just as important as clean eating.

Sleep plays such a powerful role in determining your appetite and energy levels that I believe it should be your first priority—even before you think about your diet. – Gwyneth Paltrow
