they help provide extra protection from the sun

blue light and UV rays. As Ligas notes,
MAKING
LENSES
“Often associated
exclusively with electronic devices and
screens, what most
people don’t realize is
that the sun is the single largest source of
blue light, scattering
it through the atmophere and emitting
over 100 times the
intensity of electronic
devices and screens,”
notes John Ligas, vice president, R&D,
Transitions Optical. “In fact, depending
on the time of day, a majority of outdoor visible
light you receive is blue light, which explains
why the sky itself is blue.”
