is the world really upside down?

[ColJack]

while rubbing my eye last night I noticed that if i press on one side of my eye, a dark spot appears in my vision on the opposite side , ie push bottom left - spot appears top right..

does this mean that everyting I'm seeing is really upside down?

 

[conny]

No.

We are the right way up, its just you who is topsy-turvy!

I think it's a sign that you were rubbing it too hard, a common occurrence on Saturday nights .

PS; Any news on the work front Col ?

What happens if you rub it with your other hand?

push bottom left - spot appears top right..

Got to get this mental image out of my head!!!!

zero.. I don't drink very often..
when I'm on holiday abroad, at my parents over x-mas ( 2 small glasses wine with x-mas dinner, 2-4 cans on boxing day night ), and when needs must recently for medicinal reasons ( pain relief for toothache.. )

Optically, the image our eye receives from the outside world is upside down. Our brain translates this and converts it to the right way up.
Scientists have devised experiments using a pair of goggles that turn our visual experience back the right way( upside down to what we perceive). People who wear these goggles, quickly find that their brain adjusts within a few hours, such is the power of our brains. When these people stop wearing the goggles, they quickly adjust to seeing things the way that we see them again, apparently without any ill effects. This even works if they wear goggles that turn right into left. Our brains adjust to the visual input.

Amazing but totally true.

How come some people still don't know their left from their ferking right then

Have you any evidence of this? I think you confuse how pinhole cameras work, and the human brain, and the human eye, that have evolved over many thousand of years.

Micky, although the human eye is quite a complex thing. At it's most basic, it's a pinhole video camera with a lens and iris on the front of it to enable both focus and exposure. The images you receive at the back of the eye on the retina are truly upside down. Your brain corrects this without you even noticing. Here's a link to explain it.

And the link is scientific proof? It's written by a 9 year old for kids to understand, and that's the best reference material you can find?

I've had operations on my eyes, and had parts of my eyes transplanted, and picked up much medical jargon along the way, and the above translates to bull. Blimey! Every post I've read so far has turned into a circus.

I provided a link suitable to the standard of your replies Micky. You asked for evidence that the images we see are in fact upside down.
You seem to be thinking that because we perceive things the right way up that we actually see them this way.
Quick example... Do you have a digital camera, One with the digital display screen on the back??
Or a mobile phone with a camera?
When your taking a photo and see the image on the screen, it's the right way up ? Yes?

This is because the manufacturers have already turned the screen upside down in relation to what the CCD in the camera is receiving through the lens of the camera.
I don't feel I need explain any further. Micky , you strike me as one of these people who need absolute proof before you will believe anything.


PS I can't believe it's not butter.


PPS, Can someone else explain basic optical principles to Micky???
