We know how it is: Just trying to check out the latest trends on Edeloptics’ profile
on Facebook or Instagram and suddenly you find yourself on the phone for an hour
already. An hour less of sleep doesn’t sound so dramatic, however when it extends
to another hour and time goes by, some of us get nervous like Beatrix Kiddo (Uma
Thurman) in the coffin. But where does this insomnia come from? We went to bed
because we were tired.
Of course, we are to blame. But if we want a scapegoat, we should blame “HEV“.
It’s not contagious, but HEV light has an annoying side effect. If we look at a
screen emitting HEV light for a longer time (such as that of computers,
smartphones or tablets), then we absorb high-energy blue light, which is
abbreviated as HEV (“High Energy Visible“). It only gets worse when the
surrounding brightness is also low (as with Netflix & Chill at night). Under these
circumstances, our pupils are widened, which makes them absorb even more blue
To sum it up: If we watch TV shortly before we go to bed or if we have to finish
some work on our laptops, we might find ourselves not sleeping so well. It is
already known that the reason for this is the inhibited release of the important
sleep hormone melatonin. The light displays make our bodies believe that it is
daytime instead of nighttime. That’s what we call the “digital jet lag“.
The solution? Glasses with blue light protection!
Just as sunglasses and high quality prescription glasses protect your eyes from UV
light, so do glasses with blue light filter technology. They shield our eyes from the
short-wave portion of the light spectrum (380 to 450 nm). However, the part of the
blue light spectrum, which is important and useful for vision (from 450 nm), comes
through. As in the case of a dream catcher, only positive vibes are coming through.
It not only helps us fall asleep better after looking at your smartphone or tablet, but
it also protects your eyes from permanent damage in the long term. HEV might
also be responsible for macular degeneration, usually caused by old age, or rather
increase the risk of the disease. The effects: the photoreceptors of the retina are
gradually dying, what can eventually lead to loss of vision in the worst case
scenario. Speaking of effects, it is not trivial to consider safety, especially if you like
to watch a few episodes or even binge a whole season on Netflix before going to
bed. That’s why we would recommend ordering your next prescription glasses with
blue light protection!
