Some people find it difficult to understand how we can see the world properly when the image is upside down. The right way to think about this is to adopt a computational perspective. We do not perceive what is on the retina; instead, a percept is formed through a complex chain of neural computations. A control computer does not care which way is up, and inversion of the image is the least of the brain's computational problems.
If one spells out numbers, they would have to count to One Thousand before coming across the letter "A".
