I'm with the, "No, because I can't stand the way they feel pm my face/nose/ears" group.
I have some I use for tiny things, like maps or some web sites, but reading my Kindle, I do ok with one of the 2 middle sizes, depending on light and eye fatigue.
Another reason I avoid them is that my eye doc told me that using reading glasses would speed up my need for them, because our eyes' lenses get stiffer faster if we don't exercise them to focus on near stuff.
I don't know how much that really matters, or if it's cheating by using a big font, but I figure it's as good an excuse as any.
