A lowbie pair of spectacles gives a nice amount of per, but due to the current metal/LP progression they are not nearly as big a step forward as they used to be. By the time you've got enough metal rolling (at least for small villages) to get them, you're already past the point where +6 per makes a big difference.
The big kicker is the introduction of that anvil/hammer requirement compared to legacy. If that was removed, I feel the utility of spectacles would increase again. As is I was tempted to not bother making them since that neck/face slot is often occupied by bandages anyway.
