Herring Illusion

An optical illusion is a visually perceived image that is deceptive or misleading.


Fun:**** (3.15)
Submitted By:Jake


This optical illusion was first created in 1861. Look at the two thick vertical lines. Do they look straight or curved to you? Hold a ruler up to the screen and you will see that they are indeed straight.

Posted by LiaHarley on Nov 08, 2005

Well done Braingle! Even though I held the ruler up to the screen, I still think its bent! I'm starting to doubt the fact that my ruler is straight! Thanx for this teaser!!

Posted by IMCUL4E on Nov 08, 2005

aaaahhh! they keep jumping from curved to straight!!! they're alive!! XD

Posted by signmeup74 on Nov 08, 2005

Ruler or not.
They're curved. I just can't see them as straight without the paper edge.

Posted by DummyisDumb on Nov 08, 2005

I never knew braingle had illusions!!!

Posted by lycanthrope on Nov 08, 2005

All illusions are slightly bent, warped or twisted! Could be why I like them!

Posted by FerretGirl on Nov 12, 2005

I may be totally navie, but why is it called the 'Herring' Ilusion? Was it created by some guy, [or girl!] who's last name was Herring? Or was it inspired by a herring?

Posted by tjc_13 on Nov 12, 2005

well if you stare at the lines they are straight

Posted by on Nov 16, 2005

What I thought was really cool was if you stare at the center long enough you will see an 'X' that grows then disappears! Awesome.

Posted by kalarone on Sep 18, 2006

this is really cool it really makes you look.

Posted by maingle-_- on Dec 05, 2006

Awesome! when I stared at the very center, I could force the two lines to looking straight, It was pretty cool!

Posted by Pizzazz2u on Dec 30, 2006

They ARE curved, I tell you. Even after drawing this one, myself, on some drafting paper, with a straight edge, the lines still appear curved...

Posted by cooltigerr1 on Mar 31, 2007

i've seen this one before and its fun to look at =D no the lines arre NOT curved

Posted by shawnP on Apr 02, 2007

Cool!! first look they are curved, when I blink my eyes they are straight.

Posted by luckyduck on May 27, 2007

I just squinted my eyes and they looked straight!

Posted by lilrena4ever on Jun 01, 2007

Posted by i_lov_jordan07 on Jun 10, 2007

THEY ARE CURVED!!!!!!!!!!!!!!!!!

Posted by auntiesis on Jun 12, 2007

My eyes ! My eyes ! Why is it called Herring ? These are amazing. Keep them coming .

Posted by FutureMD on Jun 18, 2007

I enjoyed this illusion... By the way, I thought it was a good idea to put a little bit on the history of the illusion here, even if it is just the date it was created.

Posted by saltydavid on Jun 28, 2007

Freaky dude!!!

I can't believe how old this one is.

Posted by ll_22225 on Aug 15, 2007

Wow, neat!
They look just slightly curved to me. When I put something straight against it, it almost looked like it moved to be straight! Like it molded to the straight edge.
I wonder if all the other little lines serve and purpose in the illusion...

Posted by emoslayer on Sep 21, 2007

you suck

Posted by 974999gec on Oct 25, 2007

nice teaser! almost freaky tthough. if you look at the center the lines look curved.

Posted by tick on Nov 30, 2007

Except when I held the ruler to my old dinosaur monitor and its curved too, lol!!!

Posted by Akatsuki_Neko on Dec 03, 2007

Other thatn that, cool illusion.

Posted by ICUB42 on Sep 16, 2008

Well, ya know, those lines kinda "breathe" when I look at it.

Posted by Lil_Dork on Apr 30, 2009


Posted by kriskris on Sep 06, 2009

Posted by Doomsday on Oct 11, 2009

you can see past these sort of illusions if you cause your vision to blur. the lines are straight.

Posted by Frada8D on Nov 02, 2009

Posted by jellybeans7645 on Jun 07, 2011

When I first glanced at it I thought the lines were straight. It was wierd.
