I used to like wearing a watch as a kid, now I can't stand it and it seems impossible to get used to again. I hate having anything strapped to me besides a backpack, really. And having to retreat to my desktop running a TV all the time isn't the most convenient… but my eyes are absolutely done with near work for awhile. If you do a lot of close focus for some reason or another -- say, a full time job's worth of time on the phone -- consider limiting now before it really interrupts your life.
