Pertaining to the eye or sight is described by which term?

• A. Optic
• B. Ocular
• C. Intraocular
• D. Emmetropia

Answer: (A)

This question tests understanding of terms related to eye and vision. The root opt- means sight or vision, and words built from it describe things connected to sight. So optic directly denotes anything pertaining to vision or the visual system, such as the optic nerve or optical methods. Ocular does mean related to the eye itself, but when the emphasis is on sight or vision as a function, optic is the more appropriate descriptor. Intraocular describes something located inside the eyeball, which is a spatial detail rather than a general relation to sight. Emmetropia refers to a normal refractive state, not to a relation to the eye or vision. Therefore, optic is the best fit for “pertaining to the eye or sight.”
