Which prefix means 'eye'?

Which prefix means 'eye'?

• A. Dacry-
• B. Hypno-
• C. Ocul-
• D. Lapar-

Answer: (C)

Understanding medical prefixes often comes down to matching the combining form to the body part it denotes. The form that signals the eye is ocul- (as in ocular or oculomotor). This makes it the best choice for a term meaning something related to the eye. In contrast, dacry- is about tears and tear ducts, hypno- means sleep, and lapar- relates to the abdomen. So ocul- clearly designates the eye, while the others point to different structures or functions. (Note that ophthalm- is another eye-related root, but in the context of a prefix meaning eye, ocul- is the standard form.)
