In our eyes we have a spot where we see nothing.
This is where the nerves go into the brain to tell us what we see. This is called the blind spot.
We almost never realise we have it, the brain fills it in for us.If the brain were not able to do that, we would never see a whole picture. A small part of it would always be invisible. Actually a rather large part of what we can see is always invisible. That which is behind us. We can look at a pretty view with a smoking factory right behind us.
Is what we see still beautiful?
