Ernest Edmund Maddox (1863 – 4 November 1933) was a British surgeon and ophthalmologist. He was a specialist in abnormal binocular vision and phorias (heterophoria in particular). He made advances in optical treatments and invented several devices to better investigate eye conditions, including Maddox rod, double prism Maddox, red glass Maddox, Maddox cross and Maddox wing. As a keen amateur astronomer he also invented the starfinder, a device to home in on stars and constellations.
