There is also visual recall of something you have seen which is slightly
different. Eidetic memory is the most extreme form.

Close your eyes and consider a nice white ceramic dinner plate with a
beautiful deep red apple sitting in the center. Can you see it? From
the side and from the top? Do you see the stem? The colors? Imagine it
slowly rotating? See the fruit fly?

Apparently that’s most people.

Using visual memory is one way to beat a classic Alzheimer's test by
imagining an apple, balanced on a ball sat on a chair. It doesn't seem
to suffer the same degradation as normal short term abstract memory.

Indeed. The people who I admire the most are composers who can image
roughly what an entire orchestra will sound like playing their newly
written score. That takes an incredible amount of aural imagining.

We also have no way of knowing if what I experience for red colour is
the same as what you see for red. Some colour blind people really do see
the world differently (most common red-green colour blindness). But the
ones with slightly extended near IR vision through 4 types of cones had
advantages in warfare since they can distinguish growing vegetation from
cut and dying vegetation that has been used for camouflage.

I suppose that being nearsighted has social-evolutionary advantages.
Some people shoot arrows, some people make arrows.
