I've lost my new glasses

[watervole]

I had my new varifocals while I was out gardening - they're only useful for some things, but they come in handy for weeding on occasion.  At some point, I put them on the bonnet of the car - both Richard and I remember that.  They're no longer there, but it's quite possible that I put them on again and put them down somewhere else.  Except that I've looked in all the obvious places where I tend to leave glasses.  (No, before you ask, the car hasn't been moved since I put them there)

I can't find them anywhere.
