When I raise my eyebrows the inner corners are lifted the most by far with the center part being raised slightly. The outer corners do not move at all. Is it because my eyes are very far apart (IPD 70mm) and the muscles do not attach to the outer parts for me? When I look at other people most people’s brows raise evenly across their whole length and some can raise the outer part only. Neither is the case with me. Do I have nerve damage or are my eyes (and brows consequently) too far apart?
