I've worn progressives for about 4 years, and haven't had any problem except on stairs. That's still tricky.

The only issue I've had is that the style lately has been for lenses to be fairly short from top to bottom, and you need a bit deeper lens for the progressives. So the most stylish glasses aren't an option, which isn't a problem for me since I'm not stylish anyway, but the selection of frames can be pretty small.
