adjustments

adjustments take time, even when that to which one adjusts happens all at once. 

picked up the new glasses today.  I knew the change would be substantial, after all I was having the magnification cranked up a couple of notches and at the same time though sticking with the concept of progressive lenses, moving the pattern higher in the frame than the previous set.  unlike fixed lenses or bifocals, progressive lenses are calibrated for three levels of magnification with a gradual transition between them.  the pattern is like this: 

(yes, the grey area represents a dead zone where not much happens). 

turns out that was rather a lot of change to take on at once; it is definitely taking a while to recalibrate the ol' eyes to the new optics.  for much of the afternoon I must have looked like a little bird, bobbing my head in search of the right attitude and angle to find the right focal length for some object.  at this stage sudden wide angle head movements are not a very good idea, I have learned this the hard way.  but however disorienting in the short term, it does represent a recovery of lost visual capability and I'm hoping that as I get used to this arrangement things will improve.  there's been room for it.

other adjustments take time to happen but even more time to notice.  when I first took up bicycling again it seemed that it just didn't have enough low gears.  but lately it seems there aren't enough high ones.  it's the same bike so somewhere along the way my own baseline must have changed without my having been aware of it.
