Which combining form is used to indicate eye or vision?

• A. Ophthalm/o
• B. Ocul/o
• C. Lip/o
• D. Myc/o

Answer: (B)

Eye-related terminology often uses ocul/o to denote the eye itself. This combining form appears in terms such as ocular and oculomotor, which directly reference the eye and its function in vision. That direct connection to the eye makes it the most fitting choice for indicating eye or vision. By contrast, lip/o means fat, myc/o means fungus, and ophthalm/o also relates to the eye but is more common in specific field names (like ophthalmology) rather than as a general combining form for eye or vision.
