The term Punctum Remotum refers to which optical landmark?

• A. Far point
• B. Near point
• C. Retinal point
• D. Focal point

Answer: (A)

Punctum remotum is the far point—the farthest distance at which an object can be seen clearly with the eye in its relaxed state. This landmark defines the limit of unaccommodated vision. For an emmetropic eye, the far point is effectively at infinity, meaning distant objects can be focused without effort. In a myopic eye, the far point sits at a finite distance in front of the eye, so very distant objects blur unless accommodation or correction is used. In a hyperopic eye, the far point lies behind the eye, so even distant objects require accommodation to bring them into focus. Thus punctum remotum specifically refers to the far point, not the near point, retinal point, or focal point.
