However, according to the technology website CNET, this effort is likely not enough to mitigate sleep problems. An investigation by the Lighting Research Council into the effectiveness of Apple’s new “Night Shift” feature demonstrated that it was not effective in preventing melatonin suppression.
The Night Shift feature came in two options, “Less Warm” (more blue light) and “More Warm” (less blue light), that changed the color scheme, but not the brightness. There was very little difference in the results- 12% melatonin suppression on “more warm” vs. 19% melatonin suppression on “less warm.” The study’s main takeaway was that changing screen color alone is insufficient, as blue light is still being emitted from the devices.
This is no surprise, while the color shift may contribute to warmer colors being shown on the screen, the brightness of the screen itself generates sufficient amounts of blue light to suppress melatonin production.
If you are looking to get to sleep, try Melatonin Production Factor (MPF) glasses. These glasses are designed to filter out melatonin suppressing blue light, allowing your body to produce the melatonin it needs to get to sleep.
]]>Welcome to The Macula Store! We are a store dedicated to impacting eye health through prevention, technologies, and education.
A pillar of eye health is blue light protection. We are happy to provide blue light filtering glasses with a TrueBlue lens.
Blue light has been shown to be harmful to both the eye and the body. In the eye, it is a leading cause of digital eye strain and, longer term, a leading cause of vision loss and as blue light destroys macular pigment.
According to The National Sleep Foundation, it can also lead to insomnia. They have also recommended shutting off electronic devices two hours before bed to fall sleep and improve the quality of their sleep. Blue light inhibits the body's ability to produce melatonin, the hormone required to get to sleep at night. A lack of sleep has been linked to weight gain, diabetes, and cancer, as the body uses sleep to suppress tumors.
Due to the advent of computers, smartphones, and LED lighting, blue light is now omnipresent and an integral part of our daily lives. We are now exposed to blue light indoors and outdoors, at home and at work and we need to limit our exposure to this light in order to prevent harmful and costly ailments down the road.
With that in mind, protect your eyes by wearing blue light filtering glasses, particularly those with a TrueBlue lens.
Our glasses come in three varieties: Indoor Protection, Night-Sleep Aid, and Sunglasses.
Indoor protection or computer glasses are the clearest set of glasses, perfect for work or home. These are perfect for everyday use, whether hard at work or relaxing at home.
The Night-Sleep Aid glasses feature a deeper yellow/orange hue, which is the extra amount needed to allow your body to produce the melatonin it needs to get to sleep at night. Not only will they help you get to sleep, but it will also improve the quality of your sleep. Wearing these glasses is an acceptable substitute to turning off electronic devices that won't throw you back to a time before electricity.
Sunglasses are probably the most familiar of our products. However, sunglasses with a TrueBlue lens not only block UV light but also filter more than 90% of blue light as well, which many other sunglasses, even the expensive ones, do not.
We'll be posting regularly, but, in the meantime, please peruse our portfolio of glasses and protect your eyesight today!
