The eye, SRH and Fractals

 

The image on the retina of an eye is upside-down and leftside-right compared with the object.

So which do we see: the object or the image? If we put on red spectacles the world becomes red. Clearly we don’t see the object--which is unaffected by the spectacles--but the red image that occurs on the retina. So likewise we actually see an upside down and leftside right world.

To test that things are the wrong way around , carefully press the bottom right of our eye ball. We will see a black spot appear on the top left of our vision. Think about this with the picture above. If we press the bottom of the retina the black spot will occur near the head of the person, in other words at what we call the top.

But we have two worlds at our disposal. There is the physical tactile world where we can lift our arm up and feel the motion against gravity in our stretch receptors. This is the same world that tells us when we move our eye ball upwards. Conventionally this the movie watcher. Then we have the other world within the image of our eyes: the conventional movie screen. The conventional view is that the movie watcher is correct and the brain “turns” the movie screen upside down and leftside right so that what we “see” corresponds to what we feel. You look at the top of the movie screen and you see the heads of actors, and the bottom the feet of actors.

However does the idea of flipping the movie screen actually achieve anything?

If we take the picture above and press at the bottom of the eye the black spot appears above the head of the person. If we now look DOWN at the feet of the person in reality the image on the retina moves DOWN so that the feet become centre on the retina. The subject actually see the person move up to move the feet into centre place of the image. If we touch the bottom of the eye ball the black spot now appears near the middle of the person. Everything works without any flipping of images.

I admit I need to consider this further to check, but so far I see no need to introduce “flipping” operation in a brain that doesn’t need them, or where they actually mean nothing. Up and Down are relative.

It has an interesting implication. If we try and work out whether things are “really” Up or Down we get into a problem. The very picture above is flipped on our retina. So what is UP becomes DOWN and vice versa. The “retina man” picture is the real UP as shown in Fig 2. However when we look at Fig 2 the “object man” is the real UP. When ever we try to represent what is happening in the eye we will get things the wrong way around compared with “reality”. This is because of SRH. The eye cannot represent its own functionality, unless that function is identity. We are using the eye in the system that is processing the eye. This is doomed to problems and fractals. Obviously we can keep duplicating, scaling a flipping these images infinitely to generate a fractal. Much like pointing a video camera at the video screen showing its image. This simply scales the image. Our lens also flips it!

 

So how do we answer it? We just have the accept that the “real” up looks down in our world. But since everything else is down, that as good as to say things are the right way around. So when a person stands on their head, their image on our retina is actually the right way around to a researcher looking at our eye. But someone should remind him that this image is upside down on his retina before he draws any conclusions about what the real “up” and “down” are!
