The science is clear...
your lenses shouldn't be!
All light is naturally balanced across a full spectrum in nature, however man-made sources of modern lighting and LED screen devices emit intense, unbalanced doses of a “fake” blue light spike on our eyes..
This un-natural SPIKE disrupts our health, and importantly--our natural Circadian Rhythm which allows our bodies to SLEEP and heal.
This can lead to damaging effects on our overall health and wellness.
Protecting your eyes is important but most blue light blocking glasses are made with near-clear lenses that fail to block the full blue light spike.
Melatonin Suppression and Mitochondrial Repair
Light enters the eye and stimulates the retina, turning it into an electrochemical signal that travels through the body down a multi-synaptic neural circuit to the pineal gland, which is responsible for producing melatonin.
A primary function of melatonin is repairing mitochondrial DNA. The damaging blue light spike measured at 455nm suppresses melatonin production. The lack of repair from this suppression leads to an accelerated accumulation of mitochondrial DNA mutations, known as “herteroplasmy.”
As mitochondrial DNA mutations increase, our body systems begin to lack the energy necessary to carry out their functions, leading to many modern chronic diseases.
The wavelength makes a difference
Visible light travels in waves. Our eyes can see wavelengths of light between approx. 400-750 nanometers (nm). Sunlight provides a broad, gentle wave of light to our eyes and can be healing to us and our daily circadian rhythm.
Modern LED lighting and screen devices we surround ourselves with however emit a large spike of blue light at 455nm. This damaging wavelength has been found to have the highest impact on melatonin suppression.
Clear lenses may only filter or block from 400nm - 420nm but they provide no protection in the most damaging range of 440nm - 455nm, you need a yellow lens to block blue.
Melanin naturally absorbs the higher energy light (UV, violet, blue) MORE STRONGLY than the lower energy light (yellow, orange red) to maintain a balance in our bodies (Blue is energizing, Red is healing, for example).
Melanin also provides near OPTIMUM PROTECTION to the retina by FILTERING the different colors of the visible light spectrum in proportion to their ability to damage tissue of the retina. More damaging = More Protection from Melanin.
