11 Optical Illusions That Will Trick Your Eyes

11 Optical Illusions That Will Trick Your Eyes

This gorgeous lady must be a ballet dancer otherwise she wouldn't be able to keep rotating like that with such grace. Like on her toes, but we're not here to discuss her artistic skills- instead, can you tell if she is moving in one or two directions? So what do you think- left or right? Both options are correct, the lady is moving in the right direction. Another illusion called the cafe wall illusion was inspired by a tiled wall in a cafe in Bristol. The dark lines seem to be parallel to each other, but they are actually inclinations; this distortion is caused by our retinal neurons and neurons in the visual cortex working together in peculiar ways. For the impossible triangle, meet the impossible triangle. But wait, what makes it so impossible? You have ten seconds to figure it out before I reveal the explanation. If you follow the ball sliding on the surface of the triangle from the top point, you will see that both sides seem to be on the same plane- an optical illusion tricks your brain into believing it's possible. Six more examples:

1) This car is moving backwards-actually it isn't! To see this illusion, you need to reverse the image on your computer so that everything looks normal from the outside.

2) Just because something seems impossible doesn't mean it actually isn't possible- for example, consider the impossible triangle (Penrose triangle). If it existed in reality, it would be contradictory to Euclidean geometry and therefore false.

3) This vase seems empty, but if you look closer you'll see that there are still some leaves floating in its water. This effect is caused by perspective; things seem smaller when they're further away from us.

4) Move your eyeball around really quickly and you might start to see multiple circles until your vision refocuses and they disappear again. This effect is called flickering; due to a phenomenon called persistence of vision, objects seem to stay visible for a brief moment after they're no longer actively being viewed.

5) Sometimes numbers can appear impossible- like this ridiculously high number 18298432129980! The reason these numbers appear fake is because our eyesight is limited; when we try to focus on an object too closely, it becomes difficult to distinguish individual numbers.

6) Notice how this person's hand disappears when they gesture? That's because of regression; since we learn primarily through our hands during childhood development, when we adults gesture (or touch something), parts of our hands often reappear again later on in our lives.

the first one is creepy this is a famous

drawing created in 1892 by Charles Alan

Gilbert called all is vanity and

depending on what you see first it can

come off as a little creepy most people

who look at it don't even realise that

the drawing is much more than it seems

have you noticed anything unusual about

this picture you have 10 seconds to

figure it out those who look at the

drawing notice either a woman sitting in

front of the vanity mirror or a spooky

looking skull if you've managed to spot

both of them right away congratulations

your visual perception is pretty

impressive alright here are hidden faces

here's another challenging image where

you have to find something that's hidden

right in plain sight now at first glance

it might look way too easy after all

everybody can clearly see at least four

faces in the tree branches but like any

optical illusion there's a catch see how

many more faces you can spot in the next

10 seconds

if you found 10 faces hidden among the

branches then you're an extremely

observant individual some say that these

faces are actually those of famous

public figures can you recognize anybody

share your ideas in the comments below a

fair lady this gorgeous lady must be a

ballerina otherwise how does she keep

rotating like that with that much grace

Oh like on her toes

but we're not here to discuss her

artistic skills instead can you tell if

she is moving in one or two directions

so what do you think

left-right both oh the correct answer is

she is moving in the right direction

cafe wall illusion the name of this

illusion was inspired by a tiled wall of

a cafe in Bristol like Starbucks nah but

I will tell you no more for now can you

tell if the dark lines are parallel to

each other or incline you have ten

seconds to figure it out

again it seemed like an easy question

the lines are so obviously inclined it

turns out that they're not let us blur

the image quite a bit more now that all

the small elements are completely

blurred you can see the dark blue lines

are actually parallel to each other well

that's not fair

this phenomenon is known as the cafe

wall illusion it was first described

more than a hundred years ago but got

its name only in the 1970s when a guy

named Steve Simpson noticed a similar

effect on the wall of a cafe in Bristol

little black and white bricks at the

intersection of wide lines make this

illusion possible curved elements inside

the blue lines only make this effect

stronger the reason we see this

distortion is that our retinal neurons

and neurons in the visual cortex work

together in quite a peculiar way number

five for the impossible triangle meet

the impossible triangle but wait what

makes it so impossible you say you have

ten seconds to figure it out before you

hear the explanation

the impossible triangle known as Penrose

triangle is so called because it can

never exist in reality if it did exist

it would be absolutely contrary to the

rules of Euclidean geometry what is so

wrong with this figure well if you

follow the ball sliding on the surface

of the triangle from the top point you

will see that the left side is extending

away and the right side is leaning

towards you however they both seem to be

on the same plane only an optical

illusion makes it seemingly possible to

the human eye now number six bicycle

okay this one seems pretty plain there

is a bicycle and it's moving still there

is something wrong here something

mysterious can you figure out what the

trick is you have ten seconds to do so

what makes the bicycle move obviously

the fact that the spokes in its wheels

are rotating now it can't be that easy

when it comes to optical illusions in

fact the spokes remain in place and the

colors that fill the wheels those 50

shades of grey that keeps changing this

illusory motion effect is created thanks

to small quick iya movements scientists

are still working on figuring out how

this phenomenon works to understand the

perception of motion better ah now i

present to you rubik's cube what are

these red and green and white lines all

about it looks like something familiar

but what exactly is it if you need more

time just pause the video

we are going to need a cylindrical

mirror to get the right answer

it's a Rubik's Cube this optical

illusion is based on an amorphous hey I

remember an amorphous she used to live

down the street actually it's a form of

perspective the idea of it is to

transform images so distorted it is

almost impossible to guess what they are

into something that makes sense

using a cylindrical mirror and it only

makes sense if you do it from one

special point so only one person can see

it at a time it would be a great way to

send hidden messages it turns out this

technique is not a 21st century 3d era

invention it actually dates back to late

Renaissance which was in the 16th

century chessboard

you can't play any chess with this board

because it's moving all over the place

or is it you have ten seconds to do so

and please try not to get hypnotised

as hard as it is to believe the eyes

actually remain where they were you can

see it if you focus on just one of them

if you stare at one point and ignore the

constant movement of black and white

dots it all becomes clear and dust away

huh counting down from number nine

upside down steve buscemi can you tell

me what's wrong with steve buscemi I

mean I hope Steve is perfectly fine but

can you tell me what's wrong with the

second picture hmm these pictures look

the same to me hit thumbs up if you

think so too let's try to turn it upside

down oh ho now that is way too scary it

seems like my eyes tricked me again by

the way here is another fun celebrity

optical illusion Hermann grid illusion

and scintillating grid illusion look at

this black square crisscross with

perpendicular white lines the white dots

situated at the intersections of the

grid shift their colour from white to

grey and back when you concentrate on a

particular dot you see that it's white

but as soon as your attention wanders

the dot turns grey that's the Hermann

grid illusion amazing isn't it we can

take this illusion one step further by

positioning white dots at the

intersections of grey lines all placed

on top of the black background look at

this image attentively and you'll notice

black dots starting to pop up at the

intersections of the grid doesn't it

create a scintillating effect another

name for this illusion is a simultaneous

light contrast illusion as you perceive

the dots as white at one moment and then

almost immediately you see them as black

how is it going have you managed to spot

this effect yet if not take your time

you can pause the video and observe this

illusion for a bit longer so why do your

senses let you down by making you see

gray or black instead of white actually

this illusion demonstrates one of the

most important principles of human

perception you don't always see things

for what they really are the thing is

that the retinal cells in your eyes act

as light receptors when only one

receptor gets illuminated it perceives

more light than when its colleagues are

also illuminated this prevents the

firing of nearby receptors as a result

the effect only gets transmitted

laterally let's see how it works with

the Hermann grid illusion the white

lines are arranged in such a way that

there's more light around the

intersections then along the lines

themselves thus the dots at the

intersections are more inhibited and you

see darker spots are you thoroughly

impressed yet well the best is yet to

come

finally consider this one boxes it takes

one large box and one little box and

some magic to make this illusion

possible I will leave some space to your

imagination here let's discuss it in the

comment section how is it possible for

the little box to be outside inside and

part of the large box at the same time

so how many optical illusions did you

manage to crack tell us in the comments
