one time i was faded and for some reason i was trying to use my peripheral vision instead of my direct sight.. and i realized that when you stare at an object without looking away and try to use your peripherals simultaneously to look at another object, you lose sight of the object your not looking away from.. i dont know, you blades should try it and see what i mean.. does your mind block it out because it is focusing on the peripheral or what??
if i take my eye off the original object i won't see it otherwise i could use my peripheral fine while looking at a original central object.
