The insignia of the Francis I. Proctor Foundation for Research in Ophthalmology is the ancient Egyptian symbol known as the "Wedjat Eye" or "the sound eye of Horus.” The symbol is derived from the ancient myth in which the eye of Horus was torn into fragments by the wicked god Seth. Later the god Thoth miraculously restored the injured eye by joining together its parts, whereby the eye regained its title as the “sound eye.” As such the Wedjat Eye represents the myth of the restoration of the eye, its parts, its precision, and the skill and art needed for its restoration. It is a symbol of great antiquity, familiar to the world's first ophthalmic specialists of Egyptian medicine.
