what most people think of when they look
at the world they think other animals
probably see the world pretty much the
same way and only with time do we
realize that of course other animals
don’t see the same things we see that
takes a sort of philosophical question
is what is the animal actually seeing
it’s impossible to know because it goes
into a brain that’s very alien to ours
it goes through processes that we don’t
use when we process visual stimuli the
animal does things with that information
that we don’t do so it’s really hard to
know the most simple eyes just tell an
animal when it’s light and when it’s
dark and then you get eyes like ours
that have color vision and very very
good spatial vision and conceive very
complex detail the development of eyes
can be categorized into four stages from
simple to complex stage one is the
simplest form light falling on just a
few photoreceptors allows an animal to
sense light and dark at stage two
organisms can now tell which direction
light is coming from in stage three two
distinct eyes appear the first is a
cupped eye with more photoreceptors the
second is a compound eye that adds more
cups both types in stage 3 can produce
crude images of objects in stage 4 the
most advanced eyes perform complex
visual tasks lenses corneas and irises
focus light on photoreceptors creating
sharp clear vision this entire evolution
from simple to complex could
theoretically happen in less than half a
million years
people have asked me if I could be any
animal at all what animal would I like
to be in terms of their vision it would
only be right to say this since I work
on them so much of my time I would
really like to know how I manage room
see the room their their perception of
the world is so different both in terms
of their sense of color their sense of
parts of the spectrum that we don’t see
it all and also the way that their their
eyes are multiple so that each eye sees
the same thing multiple times from
different points of view I think I’d
probably if I got myself into the mind
of a manager but I’d have no idea what
was going on and I would never be able
to tell myself oh this is how they see
that’s that’s the thing that I’m afraid
of but I still like to spend at least a
few minutes seeing how a management sees
the world
