How clever is the human brain?

On a recent PhotoReading course in China, I came to the section of teaching the “soft-eyed” vision look using what I call Phillip’s Sausage.

A participant said they could not see Phillip’s Sausage, and I tried every trick I knew to help them, getting a rare “Yes“, but then a “No it is not there” answer.
Both of us was getting frustrated, but keeping calm, not stressed, I searched for an answer.
The participant happened to say to me, “I am seeing you with my left eye” and then, “I am seeing you with my right eye“.
What?” How can someone at one time see with one eye and then the other, without closing an eyelid?
Then playing with my own Sausage, I noticed that the eyes where not quite aligned, they were not pointing in the same direction when looking at me. I then remembered a great British comedian Marty Feldman. (1934-1982)
Marty Feldman had a very funny eye movement that he used to his advantage as part of his comic routine.

Now, my participant was nothing as bad as the above picture, but it got me wondering, if one eye is looking at me and sending the image to the visual cortex, what is happening to the image being seen by the other eye, as that too is being received by the brain, the visual cortex?
Was the brain being selective as to which information was being processed from which eye?
The answer had to be yes. That is why I was being told that I was being seen firstly by the left eye and then by the right eye.
This attribute or condition is called Strabismus. Sometime known as lazy-eye or crossed eyes.
If the eyes cross inwards towards the nose it is known as Esotropia, and if the eyes point outwards as the picture of Marty Feldman above that is called Exotropia.
The condition is caused by the muscles of the eyes not working together, and the weaker eye’s image is often completely dismissed by the brain, a condition known as Amblyopia.
It is a common problem, and teated at an early age can be corrected, at a later age it could need surgery to correct the muscles, so often we see children with patches over the good eye, which makes the muscles of the weaker eye stronger having to work harder.
I now realised the issue as to why the participant could not see Phillip’s Sausage, and was able to put the person at ease, and enable me to relax, as Phillip’s Sausage is not deterrent to prevent you learning and being a success at PhotoReading.
Now I am impressed by the power of the human brain, and to be honest jealous of the person’s ability to control which eye they can see from.
