Super-vision
MILE 1: Your ciliary (focusing) muscles relax as you look further ahead, releasing tension; your whole eye benefits from the workout of repeated switching between near and far objects.
MILE 1000: Your daily walk has lowered your intraocular pressure (the pressure in your eye) and boosted blood flow to retina and optic nerve. You’ve reduced the chance of cataracts and slashed the risk of developing glaucoma by 73% (a serious eye condition which can lead to blindness). You’ve also increased activity in your visual cortex – meaning you see and comprehend more than pre-#walk1000miles you.
