Boeing77WI asked my optometrist about this and she says because the wire frame is quite thin, it wouldn't work or look good, unless you had a very low prescription.
KentWangLooks to be about the same as most of my actual glasses in terms of thickness. I've got a fairly hefty prescription in one eye, but all that means is I pay the extra for the thinner lenses, it's usually anywhere from $40-80 extra for the ultra thin and not all opticians supply them.
