As for glasses and driving, I am shortsighted and can see the dashboard,
even the smallest details, well enough, without glasses. But distance is
another matter. I probably can pass the standard eyesight test but why
on earth would I question whether I need glasses day by day, even minute
by minute, depending on cloud cover? (Just went horribly dark here.) Of
course I wouldn't. Wear them and be done.

But I purposely chose frameless with a cut-off at the bottom. Frameless
avoids any possibility of a frame getting in the way (even if it is not
a major issue for most people, most of the time). And the cut off means
I can see the dashboard underneath the lens which is easier on my eyes
than trying to focus through my glasses on something close.

I used to have one short sighted eye that was just right for the
dashboard, and one that couldn't read the dashboard but could see
everything outside the car clearly.

With the loss of the short sighted one, I couldn't see much of the
instrumentation (speedo was OK). So now I have bifocals with the cutoff
set to the top of the dashboard under normal driving conditions. The
prescription for distance is very weak and corrects a recent, slight, age-
related change.
