That's my point, Arvid - You may need a new prescription. I, too, have
worn glasses for some 46 years. My point is that ever since I started
shooting with rangefinder cameras, having trouble focusing was always my
first indication that my prescription had changed. ;-)

Not a bad guess, but I do use glasses and still see these problems. I 
would never be able to focus without them.
