if you have astigmatism what does your vision look like in vr
i'm going to show you a few different examples of different amounts of astigmatism
plus at the end the video what it might look like with irregular astigmatism let's focus in
so first let me show you what normal vision looks like this is where you'll have clear text
clear edges crisp edges or at least as clear and crisp as it can be in vr now let's compare
this to one diopter of astigmatism which is still considered a lower amount of astigmatism
and as you can see it's not that bad compared to normal vision you might notice that the text isn't
as crisp or clear or the edges aren't as clear they might be a little bit fuzzy but most people
that have one diopter or less of astigmatism will probably do just fine they won't really need their
correction now there are some people that might get headaches or eye strain i fatigue from having
that astigmatism if you're one of those people i would definitely wear your correction in vr
but as far as clarity goes it's not that bad now this is where we're gonna bump it up a little
bit we're gonna bump it up to two diopters of astigmatism this is where you're really gonna
notice the blur coming out a little bit if you look at text you might see that the texts are
stretched out a little bit some people might even say it's starting to look a little bit like double
vision if you see lights the lights are being stretched out edges of things are blurry and fuzzy
and you can really tell the difference when you compare it to normal vision or even the one
diopter of astigmatism this person may be really trying hard to see well squinting to make it clear
they might have eye strain and headaches now just really quick before we move on a recap of
what astigmatism is so you have nearsightedness farsightedness astigmatism which is a refractive
error that causes blurry vision and as bad as it sounds it's actually really common and about one
in three people will have astigmatism it actually feels like more to me as i'm seeing patients a lot
of people have astigmatism astigmatism comes from a certain curve to the eye that curve will make it
so your vision won't focus to a single point in fact that's what astigmatism means without point
or without spot so now we're gonna bump it up a little bit further three diopters of astigmatism
we're now getting into the higher amounts of astigmatism and this is where you'll really see
the effects that it has on the vision when you compare to normal vision you'll definitely see
that the texts aren't clear or crisp they have a stretched out appearance almost some people will
say double vision or almost a shadow is coming off those texts edges of things aren't clear and crisp
vision's distorted blurry takes a lot to know and decipher what's going on now before we keep going
i'm just curious do you have astigmatism how does it affect you in vr or in your normal life are you
wearing glasses in vr because of your astigmatism now that you have an idea of what astigmatism is
doing to the vision in vr we're gonna turn it up quite a bit here we're jumping all the way
to six diopters of astigmatism this is considered a high high amount of astigmatism and as you can
see the visual effects are really exaggerated hard to know what's going on hard to focus this person
is really having a hard time usually a six diopter person have learned the master of squinting
i've seen a lot of patients that can squint out and still see pretty well with six diopters of
astigmatism but it really tires the eyes out gives them headaches quite a bit now all those
examples were regular astigmatism eyes with regular curves to it there is something called
irregular astigmatism with an irregular curve the most common eye condition that has this is called
keratoconus where the cornea or the front clear dome of your eye instead of having a curve to
it or a normal curve actually has a cone shape to it keratoconus so here's an example of irregular
astigmatism not only do you have that distorted vision stretched out lights but you might have
stretched out vision stretched out lights coming from different angles multiple angles you might
have different halos lights will definitely look distorted and blurry really hard to tell
where the main image is people have a lot of ghost images surrounding the main image this person has
a hard time trying to squint and improve their vision because there are so many different
angles of that curve the multiple curves that you have in the eye that's causing distorted vision
now if you have astigmatism or you're curious if you have astigmatism what should you do well first
things first is definitely get your eye exam get your updated glasses prescription now if you have
one two three diopters of astigmatism or lower amounts but you have the symptoms of headaches
and eye strain you definitely want to be wearing your correction in vr now this can be glasses
soft contact lenses or my personal favorite vr prescription lens inserts you can take
your glasses prescription and order vr lenses and they can correct your astigmatism now i did
a few review videos and a comparison video in this playlist right here definitely check that
out but definitely like the video share it with somebody that you might know that has astigmatism
and they're playing vr thanks for watching I'm Dr. Neal Guymon, Dr. EyeGuy, stay focused
