Your prescription would be great for toric lenses. As long as the fit of the
contacts is checked by the prescriber, you should be able to squint, blink,
and look around as much as you like without worrying about losing the lens.
If your optometrist (or whoever you are seeing) has recommended them for
you, go for it!

In addition to the very good lens types recommended by RM, there's also the
Purevision Toric (by Bausch & Lomb), a good choice if you want to wear the
lenses for long hours every day (or even overnight). It's only just been
released for general use here (Australia), so you'd need to check its
availability where you are.
