the oculus quest 2 can be blurry
sometimes sometimes annoyingly blurry in
this video we're going to go over the
top
five reasons why the oculus quest 2
might be blurry and what you can do
about it let's focus in
[Music]
hey howdy everybody i'm dr neil gaiman
dr eye guy and i do videos
all about the eyes and what affects the
eyes and that's why i like to do videos
about
virtual reality systems or the optics of
vr
devices so let's talk about why why
this guy might be blurry sometimes
number one and we have to talk about
this one is if you are dealing with an
uncorrected prescription
if you have nearsightedness
farsightedness or the one that slips
under the radars
is astigmatism you might have
astigmatism and not really know it
astigmatism can affect the way your eyes
focus on things especially for long
periods of time
and so you want to make sure that you
have an eye exam make sure that you're
not dealing with an uncorrected
prescription because that could
definitely make
the oculus quest ii blurry if you're not
sure what astigmatism is i did a full
video on astigmatism you can check it
out right there or in the description
below for the next reasons we need to go
into a little bit more detail of how
the lenses in oculus quest 2 are made
now one of the big
challenges with a vr device is that the
device is really close to your face if
you've ever held your phone
this close to your face and try and
focus on what's on your phone
it's nearly impossible to make it clear
and so they had to come up with lenses
that could focus on something that close
and actually make it clear
in order to do that they need a high
magnification
power of lens to focus on something that
close
the problem is the lenses that have this
high magnification
are usually super thick and super heavy
and so they had to come up with
something
to make these lenses with high
magnification
but also very light so it wasn't going
to crush your nose so the oculus quest 2
actually uses something called fresnel
lenses or hybrid fresnel lenses they
have the same
huge magnification power but also very
very
thin and it still does the job and how
the fresnel lenses work instead of being
one huge magnification slab it actually
does
steps of magnification and that's why
you actually see rings
inside the lenses if you look at your
oculus quest 2
lens you'll see rings and those are
those steps
of magnification to cut down on the
thickness of the lens
and also the weight of the lens now
having explained that this brings me to
reason number two
why your oculus quest 2 might be blurry
and that is the position of the lens
the fresnel lenses leave a very very
tiny sweet spot
right in the middle that has the best
vision and the best
optics the trick there is is you need to
have that lined up
perfectly with your pupil so positioning
of the lens
is critical and you want to get the
correct ipd
the pupillary distance settings to match
up with your eyes
perfectly and i went over how you do
that in another video that i have about
eye strain from the oculus quest 2 so
make sure that you check out that video
also put a link down below of how you
can get the ipd
correct another note is not only is it
important to get it horizontally correct
to match your pupils
but vertically up and down as well if
the strap or the head device is too high
or too low
you'll be looking through a different
part of the lens and not the sweet spot
with the best vision and you'll notice
on the fresnel lenses they actually come
in rings and in the center
ring the center portion of the fresnel
lens is where you'll have
the sweet spot the best vision possible
the best
optics now the third reason actually
relates to number two
and that's to make sure the position of
the lens is as close to the eye
as possible it's the same principle as
looking through a peephole or a keyhole
if you look closer to the peephole or
closer to the keyhole
that sweet spot is going to be a much
larger view
if the lens is far away from your eye
that sweet spot is really really tiny
and you'll just get this small fraction
of clear vision
and so you want to make sure that lens
is as close to your eye as possible now
here's what's tricky is if you actually
get it too close your eyelashes will
actually rub on the lens
making the lens dirty and making the
vision blurry
so make sure it's far enough away that
your eyelashes aren't rubbing on the
lens
another tricky part is that if you wear
glasses that creates
quite a bit of space from the oculus
quest 2 lenses
and your eyes and so it's really tricky
to find that perfect balance with
glasses
to be close enough to the lenses so that
you can get a big enough sweet spot with
the best
vision and sometimes people use those
spacers into the oculus quest 2
to protect the lenses and to protect the
glasses but that can also
distance yourself distance your eyes
from the oculus quest 2 lenses
and make that sweet spot really small
and so
see if you can get your glasses as close
to the lenses as possible
without scratching the oculus quest 2
lenses
to make sure that you can see through
that sweet spot
or make that sweet spot as big as you
can now the fourth reason
why it might be blurry and i kind of
mentioned this before is if you have
something on the lenses if the lenses
are dirty even if you have the tiniest
little smudge or speck
when you are that close to the lenses
that spec is
really big and can take up quite a bit
of your view
and blur up a portion of the lens so you
want to pay particular attention
to the detail of the lenses making sure
that every inch of that lens is clean
and so to clean the lenses you want to
use a microfiber cloth something that's
not going to scratch the lenses
start in the center and do a circular
motion working your way
out towards the periphery of the lens
and that will help it keep it clean
from smudges you can also use spray but
make sure that the spray that you use is
approved
for lenses specifically so you're not
spraying some kind of
chemical under the lenses that could
warp or distort
or ruin the lenses and one thing to note
here is if you're playing the oculus
quest 2 and you're playing it for a
while
and you're one of those people that tend
to sweat or build up a lot of
perspiration then you might notice that
the lenses over time will get a little
smudgy or blurry
and that's because you'll actually build
up condensation on the surface of the
lenses
from your own perspiration or your sweat
and so every
once in a while take the device off and
see if you have a build up of
condensation
on the lenses that need to be cleaned
off now the fifth reason why you might
notice oculus quest 2
is blurry is the actual resolution or
the text resolution
in the device itself there is a way to
increase the text resolution
in the device and that's by installing
something called sidequest
and there are a lot of videos that can
explain how to do that i'll link them in
the description below
but by installing sidequests you can
increase the text resolution
it'll make the text and the picture of
the oculus quest 2
clearer but just no it's kind of tricky
because if you increase it too much you
might have performance issues and
battery issues
but there should be a good balance
between making the text
and picture clear but also running
smooth
and make sure that you check out the
description below i'll put links to
other videos down there that can help
you download sidequest
as well as other products that can help
you with the blur
from the oculus quest 2 glasses inserts
as well as
glasses spacers head straps that i like
all these things can help you find that
sweet spot in that lens
that can help clear up the device now
here are some honorable mentions of why
your oculus quest 2
might be blurry the first one is god
rays
you might notice these strips or streaks
of light
in the lenses of the device and they
call those god rays you'll probably
notice them most
coming from white text on the screen
and that is because of the actual nature
of the lenses the fresnel
lenses because of those rings of stepped
magnification
it causes those weird streaks of light
and there's really no way
around that in the oculus quest 2
because of the limitations of the lenses
that are in there
now one thing that i've noticed is that
if you turn on the night display
the blue block in the oculus quest 2 it
does cut
down on the god race it doesn't get rid
of them they're still there
but it seems to make them less
noticeable and so
try that see if you notice them a little
bit less when you turn on the night
display
of the device another honorable mention
is that your eyes actually might be
getting dry
dry eyes can actually cause blurry
vision
fluctuating blurry vision and because
you're actually staring at a screen for
a long period of time it can actually
cause the surface of your eyes to dry
out
and actually cause this fog appearance
or sometimes just
blur coming from dry eyes so make sure
that you're actually taking breaks that
you're blinking
while using the device also check out my
other video that explains more about eye
strain
from the device and i'll give you a few
tips there i'll put the link up there
also in the description below hey i hope
this answered a few questions of
why your oculus quest 2 might be blurry
i know that's one of the biggest
complaints about the device
and so i'm hoping some of these tips
helped at least make
the device a little bit clearer a little
bit more enjoyable
while you're playing the oculus quest 2.
