Protect your Eyes from Blue Light

What Is Blue Light?
High energy blue light is visible and directly
next to ultraviolet on the light spectrum. In
other words, it’s the first high-energy light in the
light spectrum that we are able to see, and it’s
only a few wavelengths away from ultraviolet
light. Blue light has a wavelength between 400-
450 nanometers, whereas UV light spans from
100-400 nanometers.
Blue light is of concern because it has more
energy per photon of light than other colors in
the visible spectrum, i.e. green or red light. Blue
light, at high enough doses, is therefore more
likely to cause damage when absorbed by various
cells in our body.
Where Is
Blue Light?
Sunlight contains blue light, but because it
contains a mixture of the complete spectrum
of visible colors, we don’t perceive the light as
being blue.
LED lights, televisions and computers, on the
other hand, emit more blue light than traditional
light sources. Blue light can stimulate your
biological circadian clock, keeping you awake,
disrupting sleep, or having adverse effects on
your circadian rhythm.
