History and use
This ophthalmoscope represents the early designs of electric ophthalmoscopes, which came with their own light source rather than relying on separate light and magnifying devices. The instrument is used by medical practitioners to examine the eye. It was made in the 1940s by Keeler Optical Products, Ltd, a British company who at that time operated out of London and Philadelphia. The object was used in a medical practice on Wickham Terrace in Brisbane by a relative of the donor.
