Drawbacks of clip-ons? They add to the weight perched on your nose.
They are also another set of lenses to collect dust (and keep clean).
They also scratch easily.

The thing I love about clip-ons is that they flip up. I can't read the screen on my
LORAN with any sunglasses. With clip-ons, I just tilt them up to read the screen
(yes, I need my regular glasses to see the thing).

The most dramatic incidence of this was when I was coming across Lake Michigan on my
last Oshkosh run. The sun was low and in my eyes, so I needed sunglasses to cut the
glare, but I couldn't see anything on the panel with the glasses on. I tilted the
clip-ons so that they covered the sky but not the instruments.

I've seen "real" sunglasses advertised in AOPA Pilot that have this feature. If they
can afford to advertise there, I expect they're pretty expensive, though. I'll stick
with the clip-ons.
