Depth Perception

[BigBoo]

me and my freind had this arguement for about an hour the otther day and we still cant agee.

if you could see from 1 eye and couldnt movve your head and were put in a strangee envoirenment could you work out how far away stuff was??

[hobbes]

No, you need to triangulate it.

well i'm getting of the age when i need the :huh: examination, so i am going to make sure the proctologist has both eyes open to get the triangulation right :o :lol:

no, with one eye you have no depth perception, how did you get into an arguement about that?

i dont agree with you SillyRumours

Without 2 eyes you cant see 3Dimensional effects
yet
you are obviously able to see distance, and will be able to distinguish between what is close and far.
if not then everything would be as flat as a comic book.

I know a guy who has one eye and for some fkd up reason he works in a company that make 3D holagrams for advertising-he is unable to see these effects but i never saw him walk into walls ;)

My uncle has been blind in 1 eye most of his life, how the hell he's allowed to drive I have no idea, but he owns a building firm and never falls off roofs or anything, I have 2 eyes and am always waliking into stuff :blink:

Oooops-i just scanned the web for
monoeyedcyclopsdepthperception

it came out with

People with one eye-have LESS Depth Perception
it is hence not true that they have No Depthperception

BigBoo-ALL your questions are answered here = http://www.losteye.com/depthper.htm


lose an eye, & you will lose some depth perception. The key is "some" which for most people turns out to be "very little".

You can help it out by practicing your one-eyed depth perception, such as by laying on your back and repeatedly throwing a tennis ball straight up in the air :blink: I have tried this & i have 2 eyes its dangerous :lol:

NontheLess my earlier statement still holds

[SillyRumours]

that's good research Zedaxax :) , it makes sense that there are levels of depth perception, now armed with this knowledge i can teach that damn cyclops down the road a lesson: he has less depth perception than me

[BigBoo]

its just one of those things that i thought of.

i said you need to triangulate and he (being almost blind in one eye) said it cant be true. i tried explaining that he triangulates by moving his head. then when we got home my brother brought focus into the arguement. :rolleyes:

Yes but focus requies depth
and if there is no depth in the world then what?
:blink:

where's fugley when you need him?

[hobbes]

Focus has no bearing on the issue of depth perception. When you chose to "look" at an object, your lens changes shape so that the "target" is in focus on your retina.

If something is close, the lens needs to bend the light more, so it thickens by contracting the muscles around the lens. If you want to look afar, the muscles relax. This is why reading can cause your eyes to tire, constant contraction of muscles.

As for depth perception, yes it is lost to some degree, but we compensate by moving our heads, understanding perspective, and other tricks.

It really affects us in fine motor actions, like threading a needle. Don't let a man with 1 eye be your plastic surgeon.

:blink: can yure brain not work out if the retina bends this much something must be this far away?
