This is a misleading summary. Humans can’t read text or distinguish fine textures in peripheral vision, but peripheral vision is very good at detecting moving objects (that’s arguably its main purpose).
I like to think of peripheral vision as “prey vision” – as in, “what would I need to know about my environment if I were a deer and a wolf might jump out at me from any side, and my main response should be to run away as soon as possible?”

- hnuser1234 8y agoNot to be rude, but yeah, what else would they mean? Is your peripheral good at picking up anything on the planet since it's always spinning? Everything is always moving relative to something else.
- jdbernard 8y agoIt's important to be explicitly clear in this case because objects traveling next to you in the road, which would be visible only in your peripheral vision, may be effectively stationary reflective to you. So you can't rely on your peripheral vision to notice them.
- hnuser1234 8y agoAh yeah, got it.
