i don't know about you guys but my parents were always yelling at me about
sitting too close to the tv blah blah blah glasses blah blah blah blah go
outside and play with your friends ma you know i don't have any friends why
do you keep bringing it up anyway back on topic is there truly a
correct distance to sit from your screen well let's start with unpacking the
claim that sitting too close to the tv is bad for your health well as it turns
out this widespread belief may have originated from a legitimate concern
over a tv recall in the 1960s where a
certain line of defective televisions actually did emit a significant amount
of x-ray radiation that is bad for your eyes
and everything else but given there haven't been any reports
of this problem since then why are people still concerned about it
well eye strain is something that you've
probably experienced after focusing on anything for a long enough period of
time even books or magazines this happens because the muscles
attached to your eyes tense up to help them focus so just like any other muscle
if you tighten them up for long enough they start to ache
and there is some truth to this effect being stronger with a backlit source if
your eyes need to be constantly adjusting between the brightness of your
screen and the sharply contrasting darkness of your room you'll experience
this eye strain fatigue more quickly
there is good news though you can slow down the effects by blinking more
frequently to moisturize your eyes glancing away from your book or monitor
periodically and by using a moderate brightness that's not too dissimilar to
the brightness of your surroundings that and eye strain is easily relieved
and doesn't cause any long-term problems as far as we know just rest your eyes
for a while by moving to a dark environment or relaxing them by not
focusing on anything too intently with that said
we still don't recommend sitting too close to your screen not because it'll
hurt you but because it'll hurt your viewing experience as we explained in
our video on retina displays which you can check out up here the correct
distance to sit from your screen is at least far enough where you can't make
out individual pixels that will make the image look blocky and distorted
so if you're in the market for a new display there's a simple way that you
can figure out what size you should buy for a 1080p display figure out how far
you'll be sitting from the screen and divide the distance by about 1.6 to get
the size of the largest tv or monitor you should purchase
you may even want to get something slightly smaller to be on the safe side
with respect to image quality but there's no reason to get something much
smaller than the formula recommends as for 4k displays the pixels are much
smaller so you can get away with buying a larger screen especially as that will
make it easier to see details that the higher resolution makes possible so for
4k your display size should be about the same as your viewing distance or just
slightly smaller and that's it once you've done some simple math
purchased the right display oh and maybe installed some bias lighting which we
covered here behind the display to improve contrast and reduce eye strain
even further you're all set to sit on your butt and stare at techquicky for as
long as you want we won't tell your mom today's episode
is brought to you by random facts about bears did you know that when bears
hibernate they actually don't have to go to the bathroom
any waste material is converted into protein
which is weird and gross
our next bear fact comes from a hunting story involving u.s president theodore
roosevelt the story goes that president roosevelt was hunting bears when his
party saw a wounded black bear cub teddy ordered a merciful death for the
cub and the story was memorialized in a political cartoon in the washington post
seizing an opportunity a new york toy store owner started manufacturing teddy
bears and the name stuck couldn't they have just like
taken to a vet that actually seems like it would have been a lot more humane
anyway the malayan sun bear is also
known as the honey bear because honeycombs and bee larvae make up such a
large part of its diet bee larva anyway you can get your very
own free bear over at tunnelbear.com
