so with our technology rapidly improving and our graphics cards and digital
cameras pumping out crisper more lifelike images than ever before it
isn't surprising that we're wondering how long it will be until we get
something that could match or exceed our eyes natural resolution or refresh rate
but what exactly are the specks of our
eyes does the question even make sense since we see things not with a camera
lens and GPU but with a squishy eyeball
and a hunk of meat inside our brain now we here at Techquickie are not the
first to answer this question in terms of discrete numbers but even so tons of
people out there are still perpetuating the same myths like the famous assertion
that the human eye can't see more than 24 frames per second which Garners eye
rolls from enthusiasts everywhere so we're going to take a stab at explaining
the truth obviously our eyes don't work exactly the same way as digital cameras
but they do operate with a few Concepts in common just like an image sensor in a
camera can capture a certain number of pixels our eyes have a finite number of
Rod and Cone cells in them plus our eyes
need different visual elements of whatever we're looking at to be small
enough so that they don't appear pixelated so in this way our eyes are
sort of kind of digital but our brains
render images we can understand by examining how the view from our eyes is
continuously changing which sounds a lot closer to how and analog technology
Works something you can learn more about up here so this means that the commonly
cited answer of 576 megapixels which was
decided upon with some rather complicated math which we've linked to in the video description needs to be
taken with some caveats don't get me wrong our eyes are indeed incredible
tools for seeing the world in detail I mean 576 megapixels is equal to having a
32,000 by 18,000 pixel monitor this
would be like having an array of over 275 1080p monitors this makes it sound
like you'd need 576 million pixels to
have a photo that fit exactly within your field of view to completely fool
you into thinking that the picture is actually real life but remember that
since you only see things sharply that are right in front of you with your
peripheral vision being a lot blurrier the actual number is only somewhere
around 8 or 9 megapixels and again since
your brains don't work in a digital manner the real number can vary quite a
bit depending on factors like ambient lighting but let's say you're less
worried about buying a camera that can match the capabilities of the human eye
and more about buying a graphics card and high refresh rate monitor that can
crank out so many FPS that your favorite game couldn't possibly appear any
smoother is that even possible well
possibly in theory a human brain could process a th000 frames per second
according to scientific Research into how quickly our neurons can fire signals
but just like the theoretical Max speeds of things like SATA drives this number
doesn't mean a whole lot in Practical terms different people have different
maximum refresh rates and the real life upper limit seems to be around 250 Hertz
depending on what study you look at but remember again that our brains and eyes
aren't exactly digital and don't render discret frames the way a graphics card
would so there is an actual number of frames your eyes can push to your brain
rather that 250 number is the point at
which motion becomes realistic looking for people with good eyesight and of
course there are diminishing returns as you approach this number for example
it's easy for most people to tell the difference between 20 and 60 FPS but 220
and 260 will be indistinguishable to a
lot of folks so while it is possible to
attach meaningful numbers to the spec sheets of our eyes and brains individual
differences along with the not quite analog or digital nature of our bodies
means that you should take them with a grain of salt and that the most
important thing is to buy stuff that will give you an experience that you
think looks good unless of course you're cool with waiting around for the world's
first 18,000 P monitor to hit the market
whoa I'm on Techquickie anyways tunnel bear VPN you can tunnel up to 20
different countries and browse the internet internet as if you are in that
country they have easy to use apps for iOS Android PC and mac and they also
have a Chrome extension just choose the country that you want in the app turn
tunnel bear on and watch as your bear tunnels your internet connection to a
new location similar to how I just came here from LTT when you turn tunnel bear
on two things happen your connection gets encrypted with AES 256bit
encryption and your public IP address gets switched so you show up to other
people as if you're in that country that you picked earlier they also have a
toprated privacy policy and do not log user activity you can try tunnel bear
VPN with 500 megabits of free data and with no credit card required and if you
decide to get the unlimited data plan you can save 10% by going to Tunnel
bear.com Linus thanks for watching Everybody give the video a like or a
dislike get subscribed if you haven't already and check out our other channel
uh Channel Super Fun where we do super fun things I'm not sure what's up there
but it's something fun go watch that I'm going to leave bye
