Description Features Original Blue Light Blocking Glasses Our most cost-effective solution to blocking blue light is the Original Blue Light Blocking Glasses. You can get all the benefits for blocking blue light without spending a fortune! Our SunDown Amber Lens has been specifically designed and proven to block 99% of blue light from 380-500nm and 43% of green light from 500-570nm from electronic devices without distorting your vision.
