Accommodation is required when the target is within which range relative to the far point?

• A. Within the far point
• B. Beyond the far point
• C. At infinity
• D. Only during reading tasks

Answer: (A)

Accommodation is the eye’s adjustment of lens power to focus on objects at different distances. The far point is the distance at which a relaxed eye can focus an image on the retina without any accommodation. When a target lies closer than this far-point distance, the eye must increase its refractive power to keep the image in focus. If the target is farther away than the far point (or effectively at infinity for a normal eye), the eye can stay relaxed and still see it clearly. So, accommodation is required for targets within the far point. The other options describe distances where no accommodation is needed or are not relevant to the concept.
