I get 20% off exams and frames+lenses as a member (life member actually) of the Cal Alumni Association. I usually schedule my visit in the summer when things are slow. It's always nice to be on campus again.

I don't think there's a reciprocation agreement. There is for library privileges. You can actually join as a UCSD alum. Life is about $750 (it was less when I joined) which has paid for itself for me. I believe there are alumni advantages at UCSF Dental as well.
