My dad lost an eye recently due to an infection that wouldn't heal and three (yes 3!) corneal transplants that wouldn't heal. Now he's got macular degeneration in his remaining eye. His field of vision grows smaller and fuzzier almost by the day. So he's having to find new ways of navigating in a world that he can see less and less of.
My physical eyesight is ok (as much as it can be 'for my age'), but we're walking through one of those valleys (or, as Holley Gerth described today, an alley) that is rather narrow and kind of dark and next to impossible to see where the next footstep will fall. I can empathize with my dad's circumstances from a spiritual perspective. I blogged about it today at 5 Minutes for Faith. Would love it if you'd hop over and check it out.
