Depth Perception

It's a strange thing to be lacking. I've mainly noticed my eyes acting up with double vision these days, but today at climbing my main issue was with depth perception. I couldn't really see where the floor was, so landing after a climb was difficult. I was dropped a couple of times when I thought I was 10cm off the ground and was actually only 1. There were also problems making footholds. For some reason the handholds were mainly ok though. Most odd.
