Putting lenses into my newly acquired polished Half-X frames, and I noticed that one of the arms only opens about 75% of what the other arm does. Its a noticable difference. I compared it to another half-x I have and both arms move exactly the same distance when opened up all the way. I took the screw out next to the lens (not the hinge screw), and with this screw out the arm will open normally. Put the screw back in, and its like the arm on that one side is bound up, like its hitting something. To help explain this better, it would be like taking a XX and putting a 15 T-shox one one side, and a 50 t-shox on the other. Anyone have any suggestions? these are brand new oakley frames and brand new oakley lenses.
