Looks to me like it's the Mirror Universe, where good and evil have been sweapped over and everypony is their diametric opposite in personality, alignment and behaviour. Notice that the Mirror Chrysalis is a pony and is evidently the Alicorn of Love. So, we can expect the Mirror Sombra to be a good guy too.

Derpy is wearing glasses so she can see straight and not crash into stuff causing endless problems. She's probably pretty fussy and perfectionist in the Mirror Universe too, once again her diametric opposite.
