so if you've ever had trouble with nighttime driving then you may have
wondered about night vision glasses these are the
yellow lenses that claim to brighten things up
and reduce glare but do they really work it's frame friday let's take a look
hey what's up this is dr allen here from the dr eye health show helping you learn
all about the eyes vision and finding the best vision products so if you're

down below so that you don't miss any of my future videos
now today we're talking about night vision glasses or nighttime driving
glasses these have been around for quite some
time originally they came out as more of shooting glasses for people
that would go out hunting for birds or sharp shooting they put on
these special yellow or orange type filters
because this type of tint kind of enhances contrast a little bit
and helps you see distant objects just a little bit easier
then that tint was turned into night vision glasses and now you see these
advertised and gas stations online a lot of places now how they are
advertised to supposed to work is that the yellow lenses will brighten
things up a little bit so that at night time you can see a little bit
easier and they also have some features to reduce glare so that you don't have
so much trouble with bright oncoming headlights which i think almost everyone
kind of does because things are turning more to led lights
you get kind of those blue and purple lights if you feel me and don't like
those either leave a comment below because yeah
they're annoying now first thing is that because these are
a tinted lens they can't brighten things up because in fact they're
limiting the amount of light entering into the eye but they kind of
give you this overall sense that things are brighter because
it's taking all of the blue light eliminating that
and really just enhancing how yellow everything looks
in complete darkness if you're driving down a
dark county road there's no overhead lights or even other cars driving
honestly it's going to make things even harder to see
these do however because of the brighting effect if you
maybe are driving at dawn dusk maybe there's snow
out and you're getting a lot of reflection off the snow and things look
almost bluish you know that kind of feeling
then these lenses do honestly make things seem brighter in those situations
and i have found myself enjoying wearing them it
kind of that low light dawn or dusk situation i've even
compared it while driving in fog taking them on or off
and found them to kind of enhance the contrast a little bit
but as far as making things easier to see at night time
sorry but no as far as the claim about headlights
i do find that helps a little bit i myself am very light sensitive i do get
migraines a couple times a year and the overall kind of feeling of that
blue oncoming headlight is pretty bothersome so this does at
least make them look more yellow kind of the old 1970s car
headlights look if you remember what that looks like
another cool benefit to some of the brands that are out there whether you're
getting dedicated ones you're getting clip-ons like these
or if you're requesting a yellow tint put into your regular glasses
these ones do have a polarized filter in them it's not 100 like polarized
sunglasses but it does have that polarized filter
which reduces glare when you're looking at kind of wet
horizontal surfaces like a wet dark road for example or
perhaps looking at water that's running that's resting on the road that
polarized filter will help eliminate light from headlights
bouncing off the wet road and then bouncing up and hitting you in the eye
and i can kind of show you that here because my computer behind me has a
polarized filter in it and you can see if i hold it this direction
the polarized filters are lined up so it's pretty
light yellow but if i turn it 90 degrees you can see it get a darker yellow
and that's because the polarized filter of the computer and the polarized filter
and the glasses are now polarized against each other now
i have read some people's comments on previous videos saying that
nighttime driving glasses really help them drive better at nighttime
however consider a recent study done about 2019
where 22 test subjects were tested with and without nighttime diving glasses
in a driving simulator and failed to show improvement
of the nighttime driving glasses versus just clear lenses
so that casts a lot of doubt in my mind that these in fact
help people see better but i can believe that they help people feel more
comfortable as i've had patients come in and
specifically request yes they want this type of tint in a
separate pair of glasses just for driving because
it really does help them but at that same time i have had people
try them i've asked them myself and they even said no they don't really help them
so i do pass that off to you leave a comment below if you've tried
night vision glasses let me know if you think they really help yay nay what are
your thoughts about them what myself and most other eye doctors
do recommend if you're having trouble with nighttime driving is to think about
what is in front of you make sure that you are cleaning your
windshield that your windshield is clean of
debris and any sort of maybe skin oils either on the front or the back surface
of the windshield if you are wearing glasses make sure
that those are clean and consider making sure you have some form of high quality
anti-reflective in those glasses that may help a little
bit and make sure that your headlights
themselves are really clean especially if you're having trouble if you feel
like things are just way too dark and that
you just can't see anything definitely make sure your headlights are clean
because sometimes they get dirty too otherwise if you feel like your vision
is changing and your nighttime driving is becoming unsafe
and you don't feel comfortable driving definitely make sure you see our eye
doctor because there are certain eye conditions that
can be leading to vision issues at night time things like
cataracts and even potentially macular degeneration
again speak with your eye doctor so for my final verdict
do they work honestly i'm very doubtful i don't think they really work but i
know they can help some people so i think if you're
really light sensitive you can give them a try but
certainly don't expect that they're gonna brighten things up and it's gonna
be like driving during daytime hey if you like this video smash that
