Which of the following is NOT true?

• A. The distal point for contact lenses and spectacles is infinity as long as it properly corrected
• B. The near point involved maximum accommodation
• C. The proximal point is closer in glasses compared to contact lenses in a hyperope
• D. The Far point is located at the focal point of the refractive error

Answer: (C)

Think in terms of how each correction device changes the way the eye has to accommodate for objects at different distances. Distal (far) points and far points behave such that with proper correction the eye can focus distant objects with relaxed accommodation, so the far point effectively moves to infinity. The near point is the closest distance at which the eye can focus with its maximum accommodation.

The proximal point is the distance at which the eye just begins to engage accommodation for a near target under a given correction. In a hyperope, placing the correction right on the eye with contact lenses brings the corrective power very close to the eye, which tends to reduce the accommodative demand for near tasks and typically moves the proximal threshold closer to the eye. When the correction is held farther from the eye, as with spectacles (vertex distance), the eye must accommodate more for the same near target, pushing that proximal limit slightly farther away from the eye. Therefore the statement that the proximal point is closer in glasses than in contact lenses isn’t correct. The far point remains at infinity when properly corrected, and the near point reflects the maximum accommodation, so option describing the proximal point as closer with glasses is not true.
