I did, but I was going when I did so. Spent more time outdoor looking far, then close, then far, etc. I've become aware of the duration of the transition in focus and it now serves as a warning side. Whenever it seems to take longer to focus on far-away things I know I need to do some more exercice. Went from needing glasses (which I declined) and seeing everything blurry to having a great vision I can't complain about.
