blue light comes from the sun. Artificial blue light comes
from our digital devices and lights like LED.

Will blue light damage your eyes?

Light for almost 50 years. The most recent evidence is

may cause damage to your eyes.
Will blue light filters and blocking
lenses make a difference?
Many claims have been made about the benefits of
blue light filters and blocking lenses. In October 2018

improve visual performance, alleviate the symptoms of
eye fatigue or visual discomfort, improve sleep quality or
conserve macula health
