Absolutely.
If you trace the light rays, you'll see that a mirror functions just like an
opening you look through; the further it is from you, the narrower your angle
of view.
A convex lens will cause the rays to converge (which is "diverge" from the
point of view of your eye), thus widening that field of view.
I'd say that for mirrors that far away from the eye, convex is essential. Of
course, I'd say a lot of things. :-)
