He was an army surgeon. ==Early life and career== Ishihara graduated from medicine in 1905 on a military scholarship〔(【引用サイトリンク】url=http://www.whonamedit.com/doctor.cfm/2765.html )〕 and immediately joined the Imperial Japanese Army as a doctor, serving mainly as a surgeon. He later changed specialties to ophthalmology. In 1908 he returned to the University of Tokyo where he dedicated himself to ophthalmic research. In 1910 he became an instructor at the Army Medical College. There, in addition to seeing patients, he conducted research on "battlefield ophthalmology" and how to select superior soldiers. While working at the Military Medical School he was asked to devise a test to screen military recruits for abnormalities of color vision. His assistant was a color blind physician who helped him test the plates. The first charts were hand painted by Ishihara in water colors using hiragana symbols.
