symptoms everything from sore eyes to poor sleep

today talking about what blue light is and the difference
between natural and artificial blue light
then we will get into the pros and the cons
and we will finally finish off talking about blue light blocking glasses
and how to know which type is suitable for you
what is blue light blue light is a color on the visible light
spectrum it is one of the highest energy wavelengths and this is significant
because the higher energy the more it can affect your eyes blue
light comes in two forms natural and artificial natural blue
light is emitted from the sun and as it travels through the atmosphere
it collides with the air molecules causing blue light to spread everywhere
and this is what makes the sky look blue artificial blue light is emitted off our
electronic devices our laptops our cell phones our tvs
and also fluorescent and led light bulbs the pros of blue light as i just
mentioned blue light is emitted from the sun
and this is natural blue light natural blue light
helps the body regulate our circadian rhythm
exposure to blue light signals your body it is daytime
whereas a lack of blue light does the opposite and signals your body it is
time to wind down for bed blue light boosts your alertness and
your reaction time we need natural blue light exposure
during the day in order to function optimally
this is one of the reasons why if you spend all day in a dark room
you can become tired lethargic and even sad blue light has also been shown to
boost happiness levels the cons of blue light as i said earlier
our electronic devices emit blue light and this is
artificial blue light in today's modern world
we're staring into these devices all day long
and sometimes even well into the night and this
is where we run into issues because blue light signals your body that it is
daytime and it boosts alertness when we are on our devices in
the evening after sunset this can cause confusion when we are
exposed to blue light the hormone melatonin is blocked
melatonin is what makes you sleepy and is usually released in the evening
if you are staring at your devices in the evening you might have a hard
time falling asleep and probably waking up as well since
your circadian rhythm will be thrown off but poor sleep is just the beginning
artificial blue light can also cause digital eye strain which can cause sore
itchy eyes headaches and progress to macular
degeneration over time when we are exposed to natural blue
light from the sun we are also exposed to
all the other colors on the light spectrum but the light coming off our
devices is highly concentrated blue light which
is why it can be so damaging for our eyes
artificial blue light has also been linked to an increased disease risk a
poornate sleep can also really mess with your hormones and lead
to weight gain as well when we get a poor night's sleep we
become temporarily insulin resistant when we are insulin resistant it is very
difficult to lose and maintain our weight our hunger
hormones are also impacted which makes the problem worse
so what is the solution ideally we want to increase
natural blue light exposure during the day and we want to
decrease artificial blue light exposure at all times but especially at night so
now we know that we are exposed to excessive amounts of
artificial blue light from our devices but it is near impossible to live
without them in this day and age and this is where
blue box comes in blue box is determined to find the
antidote to our modern digital world their two products that we're going to
be talking about and comparing today are their blue light computer glasses
and their sleep plus glasses both of these are blue light glasses but
one of them has a clear lens and one has a red lens
so what's the difference the blue light computer glasses are designed to be worn
during the day when we're exposed to artificial blue light
these glasses filter down blue light but do not block it entirely
they specifically target the 450 and below spectrum of blue light
leaving the other beneficial wavelengths alone as previously mentioned
some balanced blue light during the day is essential for our health
it's the concentrated doses that are the problem i use the blue light computer
glasses when i'm working on my computer editing
videos for hours on end and i find that they really help my eyes
to not become dry and itchy which is something i used
to struggle with the sleep plus glasses are designed to
be worn two to three hours before you plan on going to bed
these eliminate 100 of blue light that has been shown in clinical trials to
disrupt melatonin and negatively impact our sleep wearing
these before bed can help to sink your circadian rhythm
allowing your body to produce melatonin at the correct time
and fall asleep with ease i swear by these glasses
i put them on every evening at sunset and wear them until i go to bed
not only do i find they help me fall asleep faster
but they also help to improve my sleep quality
now neither is necessarily better than the other
they both serve a different purpose if you are someone who works outside
and doesn't get a lot of artificial blue light exposure during the day
then you probably don't need the blue light computer glasses
but if you are someone who works in an office under
led lights and you're staring at a screen all day long
these are a lifesaver the sleep plus glasses however
i think everyone could benefit from these unless you're in your house with
the lights off after sunset not using any of your devices you're
probably going to be exposed to a lot of blue light in the evening and
if you are someone who has trouble falling asleep or staying asleep these
will benefit you greatly blueblox has a wide selection of
stylish frames to choose from and they also offer an option for
prescription lenses if you want to check them out you can

of reading glasses to someone in need in a third world
