Ophthalmoscope: Standard Lister-Morton model, battery powered.
An instrument for examining the interior structures of the eye, especially the retina, consisting essentially of a mirror that reflects light into the eye and a central hole through which the eye is examined.
Stanford Morton was an ophthalmologist active during the late 19th century. He designed a new style of ophthalmoscope during the 1880s, which would have shone light on the eye via several mirrors. The original design remained unchanged for over 100 years, with one slight variation being the Lister-Morton ophthalmoscope.
This Lister-Morton ophthalmoscope is powered by a battery, which illuminates the eye via a built-in torch. The Lister spoken of in the title of this instrument is not Sir Joseph Lister, but his nephew, Sir William Tindall Lister. He was the one who added an electrical component to Morton's classic model of the ophthalmoscope.
