I think the lensmaker's equation is pretty par for the course for most advanced physics classes in high school, no?

  Over here in The Netherlands it was also definitely part of our physics course, I believe taught around the age of 14 or 15.

    Interesting. This is on the young side internationally. FWIW the Dutch have also been global leaders in optics for most history (the field really only starts when the Dutch invented the telescope and the microscope).

      Add a point: in Japan (also where lens manufacturers HQ'd), it's taught in high school and only for who chose physics, but some basics are told in junior high school for everyone.
