At -6.75, the impact of the shrinkage caused by eyeglasses would very likely exceed any slight visual imperfections caused by contacts (glare, halos, instability, rotation misalignment for astigmatism, etc.) I'm at -4 and prefer contacts for computer use, but it's right on the point of almost indifference for me.
