Sample item

What refractive error focuses light behind the retina?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Hypermetropia

Hypermetropia occurs when optical power is insufficient or the eye is short, causing parallel rays to focus behind the retina unless accommodation compensates.

Option by option

  • A. Astigmatism

    Astigmatism causes different focal planes across meridians.

  • B. Hypermetropia (correct)

    Correct: hypermetropia focuses light behind the retina.

  • C. Amblyopia

    Amblyopia is reduced visual development, not a refractive state.

  • D. Myopia

    Myopia focuses light in front of retina.
