To put it simply.. they actually work!
NaturoBlocks uses professional quality pigment-infused lenses that are lab-tested and verified to block out the proper spectrum and amount of blue light to protect you from the damaging effects of artificial light emitted from technology.
NaturoBlocks Energy Glasses are proven to block 88% of harmful blue light between 400-460nm (the most damaging spectrum of blue light), and block 60% of 455nm, the primary wavelength emitted from screens. Blocking this amount and spectrum of blue light has been shown in research to significantly decrease eye strain, headaches and sleep disturbances while improving mood and energy levels.
The majority of other blue blocking glasses are highly ineffective for two reasons:
They block a very small percentage of blue light (3-9% on average).
They don't even come close to blocking the damaging wavelengths of blue light that are actually emitted from screens and digital devices (455nm).
In other words they do not block enough blue and they block the wrong type of blue light. If the lens is totally clear, it is NOT blocking the right type of blue light. Don’t be fooled by “blue light blocking” marketing tactics!
