These notes focus on key factors which contribute to shaping what we see. The distinctiveness of human vision It is worth reminding ourselves that 'the world' which we often regard as objectively 'out there' is experienced in very different ways by other creatures. Sight dominates the way we 'see' the world. It even dominates our descriptive vocabulary. Of course, some creatures don't 'see' the world at all.
Most mammals live in more of a world of scent than of sight.
We share our reliance on sight more than scent with other primates. However, of all vertebrate animals, birds are the most dependent on sight. Flies have what are called 'compound eyes', but it's likely to be a myth that they see multiple images. However, if we had the eyes of a fly we would see television images as separate frames, since TV images are displayed at 25 frames per second, which for the rapid scanning eye of the fly is quite slow. Although the image can be misleading, our eyes are typically described in contrast to 'compound eyes' as being 'camera-style' eyes.
