man this oculus quest is a blast but boy can it do a number on your eyes in this video i'm going to
go over my tips to set up the oculus 2 correctly so that it can save your eyeballs i'm going to
show you how to set up the ipd to match your eyes protect your eyes from the blue light and
digital eye strain and how to keep your eyes from burning watering and getting dry let's focus in
hey howdy everybody this is dr neal guymon, dr eyeguy with a show that keeps your eyes healthy
and your vision clear and if you haven't seen any of my videos before i make videos
all about the eyes a lot of educational videos as well as how-to videos kind of like this one
so consider subscribing for my future videos otherwise let's focus on how to save your eyeballs
from the oculus quest 2. now right out of the box you want to set up the ipd settings correctly
ipd stands for interpupillary distance it's basically the distance between the center of your
pupils you can actually measure your pd at home in fact there are some apps that you can download on
your phone and i'll measure the pd for you i'll put a few of them down the link below so you can
check that out there's actually a manual way that you can do this at home easy way to do it is to
get eight inches in front of a mirror you're going to grab a ruler and place it right above your eyes
right up against your eyebrows now close your right eye and start the ruler in the center of
the pupil of your left eye now once you have that lined up keep the ruler in the same spot close
your left eye and open your right eye and measure where the center of your pupil is in your right
eye and that is your pd or your pupillary distance now the oculus quest 2 has three different ipd
settings 58 63 and 68 millimeters so you want to pick the best setting that matches your pupillary
distance this will put the lenses in direct center of your eyes that will give you the best vision
also cut down on eye strand while you're looking through the vr system now what happens when your
pupils are different from the settings that they provide here what they say to do is just
try and match as closely as possible so for me my pupils are 64 millimeters apart so i pick the 63
millimeters and actually works quite well for me now let's say it's 65 and the setting 6368 just
is not working there is actually a trick that you can do you can see other videos about this but you
can actually maneuver the lens between the setting two and setting three mark and actually stay there
quite well some people thinks it works great some people say it doesn't work because sometimes the
actual system doesn't match with the setting and so you'll just have to try it out see which
way works better for you now the next setting you want to set up is trying to reduce the digital eye
strain and blue light that comes from the oculus quest 2. now this is a question i get all of the
time in the clinic is how blue light affects your eyes in fact i'm making a series of videos
about blue light how it affects your eyes how to protect your eyes from blue light
i'll provide a link up there as well as below so as i'm adding videos to the series you can check
that out now what's nice about the oculus quest 2 it actually provides a night mode in the vr system
similar to how your phones or ipads or computers have a blue light filter or a night mode in them
the oculus quest 2 does the same thing now they've actually made it really easy to set it up on your
device if you open up the home screen on the bottom right you'll see the settings click into
that second one down is device click that second option down is night mode and you turn it on
now it's going to turn the display a little bit more of a warm color provide more orange colors
and cut out the blue light it's kind of weird at first it took a little bit to get used to
but i was able to get used to it in fact i stopped even noticing it after a while
so i definitely recommend that now the reason why they call it night mode is because it's been
proven that blue light affects your biological clock or your sleep patterns if you're exposed to
blue light especially later in the evenings it can cause your brain to suppress melatonin and it'll
make it trickier to fall asleep now i do recommend if you wear glasses normally i would say wear
glasses while you're using the oculus quest too that will cut down on the eye strain especially if
you have astigmatism also if you have a blue block blue filter on your glasses already even better
it will cut down on the blue light coming from the device they actually make attachments that
you can put on the lenses to protect the oculus quest 2 lenses and your glasses from each other
as well as attachments or inserts of extra blue filter lenses that you can put in there to protect
your eyes and i'll put a link down below so you can check those out now third thing this is the
one that actually affects my eyes the most this thing will dry my eyes out like crazy if i don't
have it set up correctly there's two things that this can actually do to cause your eyes to burn
water and get dry one you're going to be staring at a device that's kind of like staring at your
computer your phone or your ipad when you're staring and focusing on something your blink
rate slows way down so your eyes will be just open causing your eyes to get more dry and burn
and sting and sometimes water also if you don't have it set up correctly a lot of the weight of
the device will be placed on your cheekbones and actually pull your lower eyelid down if that pulls
your eyelid down it keeps your eyes from blinking correctly it also will dry out that lower portion
of your eye because it doesn't have any eyelid protecting it or covering it also it causes the
tears to flow out the sides of your eyes because the tears don't know where to go when your eyelid
is pulled down first thing you can do to counter attack that is take advantage of the 20 20 20 rule
every 20 minutes take a 20 second break look 20 feet away the idea behind that is every 20 minutes
or so take the device off blink re-coat your eyes with fresh tears look far away relax your eyes
and then you can go back at it at it again now this will help also with the digital eye strain
from the strangest looking at the device also with the dryness now what's tricky about this is
not a lot of people are going to do that because 20 minutes goes by like that in this thing but
the idea behind it is if you can just remember to blink take breaks that's gonna help with the
dryness and the digital eye strain the next thing that you can do is a simple hack with a
head strap to keep the weight off of your cheeks the secret here is all in the top head strap
you want to try and tighten that top head strap to pull it up just a little bit to take the weight
off the top of your cheek so it's not pulling your eyelid down another thing that you can remember is
if your eyes aren't really feeling dry and burning make sure that you actually use artificial tears
every once in a while it's kind of like putting lotion on your hands if your eyes are dry
it just wants another extra coat of refreshing tears and that will keep your eyes nice and
healthy hey if you found value out of this video for saving your eyeballs from the oculus
