Julius Hirschberg (18 September 1843 – 17 February 1925) was a German ophthalmologist and medical historian. He was of Jewish ancestry.
In 1875, Hirschberg coined the term "campimetry" for the measurement of the visual field on a flat surface (tangent screen test) and in 1879 he became the first to use an electromagnet to remove metallic foreign bodies from the eye. In 1886, he developed the Hirschberg test for measuring strabismus. His series Geschichte der Augenheilkunde (History of Ophthalmology), nine volumes written from 1899 to 1917, is considered by some to be one of his greatest achievements.
