When it comes to improving your sleep it's essential to choose the best blue light glasses.
Unfortunately, the market is awash with a lot of blue light glasses that will not even remotely help improve your sleep.
So you first must understand what frequencies of light your blue light glasses should block in order to improve sleep.
Blue light and some green light is disrupting your sleep and has been linked to issues such as diabetes, obesity, neurological and heart disease according to Harvard Health.
Blue light has been shown to disrupt your melatonin production, increase cortisol levels and not allow you to sleep properly.
The Melatonin Disruption Zone
Melatonin is our sleep hormone and also a powerful antioxidant that is needed to repair cells in our bodies and keep our mitochondria (cell batteries) from damage. Blue light and green light turn down our natural production of melatonin when we are exposed to it after dark, this is what disrupts our sleep and limits our bodies from repairing themselves.
In order to achieve optimal sleep and more melatonin production we must block 100% of the light found to disrupt melatonin production.
In 2001 a peer reviewed study was released called “Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor”.
In this study the melatonin disruption curve was identified. What this means is the range of light that turns down your melatonin disruption and destroys your sleep.
The academics came to the below conclusions from the study and graph.
- Blue light was determined to have the strongest effect on melatonin suppression. Specifically, between 440-480nm (upper blue)
- The spectral range of 450-550nm provided the strongest stimulation of circadian disruption (upper blue light and majority of green light)
- Light post 550nm had very little, if any effect on melatonin secretion.
- The perfect range of light to block for improving sleep would be all blue light and most green light. 100% of the light that falls between 400-550nm.
But What Blue Light Glasses Do I Need?
So now we know what light we need to block to get better sleep; blue light and green light between 400-550nm.
Therefore, if you want to improve your sleep you must have blue light glasses that block 100% in this range. If you have blue light glasses already you can test them instantly by clicking here.
If you are looking to buy blue blocker glasses that help you sleep then you need to figure out whether the company you are buying them from blocks 100% of blue light and most green light as well.
Send the company an email before you buy your blue light blocking glasses and ask them how much light their blue light glasses block between 400-550nm. If it’s any less than 100% avoid buying them as you won’t be getting optimal sleep. We did a review of some of the top brand's lens spectral analysis reports.
Blue light blocking glasses that help with sleep are typically a deep orange or red colour. They are this colour as this colour is the only colour that can block 100% of light between 400 to 550nm. Many companies claim their blue light glasses help with sleep, yet they have a clear of yellow lens. It is 100% impossible to block 100% of light between 400-550nm with a clear or yellow lens. Don’t believe me, then try our test here with your clear lens blue light glasses.
Clear lenses are computer glasses and work during the day to help digital eye strain but they cannot help improve your sleep. Yellow lenses are also daytime lenses to help with anxiety, depression or migraines and can also double as gaming glasses, but they will not help improve your sleep, this is scientific fact!
Why BLUblox Sleep+ Lenses Are the Best Blue Light Glasses
The evidence speaks for itself in order to choose the right blue blocking glasses for better sleep you must block 100% of light between 400-550nm. As you can see from the lens test report below, BLUblox Sleep+ lenses block exactly 100% of light between 400-550nm.
These make them hands down the right blue blocking glasses for better sleep. Ensuring your blue blocking glasses are backed by science is critical in ensuring you get the best blue light glasses. You do not want to be wasting your money on a pair of blue light glasses that do not help your sleep, “buy cheap and buy twice” is the famous saying.
