OD Symbol - Optometry and the Caduceus Medical Emblem #3063064 (License: Personal Use)

This black-and-white emblem features the caduceus-a staff entwined by two serpents and topped with wings-flanked by the bold capital letters “O” and “D,” denoting Doctor of Optometry. Though historically associated with commerce (Hermes), the caduceus is widely adopted in U.S. healthcare, including optometry, despite the more accurate Rod of Asclepius being preferred in medicine. The design conveys professionalism, vision care expertise, and clinical authority.

Commonly used on optometry clinic signage, professional websites, licensing materials, and educational content; matches user intent for identifying optometric services, understanding professional credentials, or researching eye care symbols.
