Which of the following is true in regards to hyperopia?
Patient would be unable to pass the Snellen exam.
Difficulty seeing from far or at a distance.
Inability to see objects or letters close in range.
Patient most likely will pass the Rosenbaum chart.
The Correct Answer is C
Choice A rationale
Patients with hyperopia (farsightedness) are able to see distant objects clearly but may have difficulty focusing on near objects. They can pass the Snellen exam, which measures distance vision, but may struggle with close-up tasks.
Choice B rationale
Hyperopia involves difficulty seeing close objects, not distant ones. Therefore, patients with hyperopia would not have difficulty seeing from far or at a distance, making this statement incorrect.
Choice C rationale
Hyperopia, or farsightedness, is characterized by the inability to see objects or letters that are close in range. It occurs when the eye's shape causes light to focus behind the retina instead of directly on it, leading to blurred near vision. Corrective lenses can help focus light properly on the retina.
Choice D rationale
The Rosenbaum chart is used to assess near vision acuity, which would highlight issues with hyperopia. However, patients with hyperopia would pass the Snellen exam, which tests distance vision, but might struggle with the Rosenbaum chart. .

This condition progressively impairs the ability to see fine details and perform activities like reading or recognizing faces.
Choice D rationale
