The chances of UV radiation making it all the way through the glass
lens, through the glass mirror to the silvered backing, through the
glass of the mirror again and halfway through the glass lens again
are slight. But it can't hurt... Also, if you hold the lens a foot
away from the (front surfaced) mirror, twice as much UV radiation
should be coming at the lens.
