Model of an eye, Europe, 1801-1900
The crystal part of this model shows the vitreous humour – the jelly-like substance that fills the eyeball behind the lens. The copper covering represents the sclera, the hard white coating of the eye. This model may have been used to help teach medical students about the basic anatomy of the eye and about how light travels through the front of the eye into the vitreous humour.
