Was checking out a few of the links posted and most of the glasses look like normal glasses. I was thinking cycling glasses were a more distinct type of glasses like these:

The glass curves around to protect from wind and debris, lenses are "higher" up to compensate for looking up when in the more aggressive positions, and some kind of magic material on the nose that keeps it from sliding down or moving much at all.
I've ridden for many years with just normal prescription glasses and have always suffered from them sliding down my face, or when they do stay put with the use of a strap, not being "high" enough that I end up looking over them when in the drops. Was aiming to get something more tailored to cycling.
