I don't know why but so far, every single female character I've encountered in the game has glasses.

I've tried starting a new vault several times, in each case every single new female vault dweller had glasses, so do all their female children and even the raiders. It's uncanny.

I don't have anything against glasses I'd like to know why this keeps happening and preferably I'd like it to stop happening for the sake of variety.

It seems like the only dwellers in v1.3 that don't have glasses are those with facial hair. So now all of the women have glasses.
