Reference. Book. The Sense of Order

I am working on the experience of awarensss, and there are some information from the text that takes part,

‘Hogarth was right in reminding us of the limited span of focused vision, The Fovea Centralis, which is alone capable of sharp definition, covers less than one degree, while the remainder of our visual field appears progressively indistinct the further it is removed from the fovea. Unlike the limits of resolution, this unevenness of our vision rarely obtrudes on our awareness, because we can always fix on any point that interests us, and since the eyes are very mobile we can build up a detailed picture of any object we wish to inspect…’

(Reading : The Perception of Order, page 96)

This is a picture of Foveated image from digital camera which shows a narrow focusing point at the center of the picture. Our eyes also see things like this but they are mobile, so they are able to build up a detailed picture of what we are looking at.

According to the text, our eyes work quickly to create a detailed picture of what we inspect, but what if we just focus on one thing for a very long time, which i have tried myself by looking at a desktop for a while, then what i see is that everything behind and around my desktop goes blurry. This could mean that if we are focusing on something for a long time, we also lose our perception to the surrounding, which means that we are barely aware of the surrounding.

If we read a book while walking, you are getting a higher chance to bump with people in front of you, because you are aware of what is in the book, but not the surrounding.
