Blue light emitted from the sun is essential to your body’s ability to maintain circadian rhythm.
However, the artificial blue light (HEV) that beams into our eyes on a daily basis from our computers, smart phones and digital devices may be keeping us awake at night and causing undue strain. This is why we now have the technology to protect our eyes and enhance comfort with new options in lens selection.
Blocking UV and HEV light (High-Energy Visible Light) is critical for protecting eyes against cataracts and age related macular degeneration which is now possible with Blue light protection.
There are many different options from blocking UV and filtering out the highest energy portion of the visible light spectrum indoors to transition for blocking of harmful blue light outdoors which are also available in polarized options.
