Improper Bone

Let me just admit: I've not worked with Sims meshes before. I abit with Zoo Tycoon 2, but nothing serious. I have been wanting my make a set of characters from the show Good Omens, and I challenged myself to use only game assets or things I myself can make. Well. Crowley needed some blinder sunglasses, so I decided to mesh it. Not sure what exactly I did wrong, but the frames sit just fine, but the lenses will be anywhere from inside the Sims eyes to right where they are supposed to be. I didn't notice at first, but The Sims Resource told me that it was because I had it assigned to the wrong bones. I double checked, and the bones I had the glasses assigned to were head for the frames, and glasses, for the lenses, because there was no head bone. I checked to make sure that was the bone with the weight. I am honestly at a lost for what I did wrong. link Here is the package file. It has LODs, texture, and everything, just can't get the frames to sit right and would really love to learn how. Honestly, I have another pair to make, and I want to get into other meshes as well.
