“Central eyesight, which allows us to “see” an object, is the last and slowest visual pathway to be activated during processing and yet, mistakenly, the most common way of evaluating visual function. Other pathways include peripheral eyesight that allows the brain to set a context for such objects, and many non-image-forming retinal pathways that link the external environment to internal systems that control sentience and metabolism. This last group of pathways is routed beneath conscious awareness directly from the retina to the body and affects such critical systems as balance, posture, hormones, neurotransmitters, circadian rhythms, etc. The interaction of all the non-image-forming signaling pathways modulates peripheral eyesight, and in turn the efficiency of central eyesight.
