The combined refractory effects of the different parts of the eye form an image on the retina that is different from what your brain interprets. How does the image appear before our brain changes it?

The image is reversed from left to right, reduced in size and inverted (upside-down)

Explanation:

The light rays entering the eye usually change as they leave the air and go into the eye structure, this phenomenon is known as refraction

The combined refractory effects of the different parts of the eye form an image on the retina that is different from what your brain interprets. Before our brain changes it, the image is reversed from left to right, reduced in size and inverted (upside-down).

However, we do not see these images because the brain has adapted and been trained early in life (infant stage) to learn to coordinate pictorial information or visual images with respect to the location of an object. Therefore, the brain is saddled with the responsibility of quickly re-arranging the object so that the inverted (upside-down) nature isn't noticed.
