Which correction is generally not needed for a patient with emmetropia?

  1. Glasses for distance vision

  2. Glasses for near vision

  3. No corrective lenses are required

  4. Contact lenses

The correct answer is: No corrective lenses are required

Patients with emmetropia have normal vision, meaning their eyes can focus light correctly on the retina without the need for corrective lenses. As a result, these patients do not require any corrective lenses for either distance or near vision. This is why the correct answer indicates that no corrective lenses are required. In this context, options suggesting the need for glasses for distance vision, glasses for near vision, or contact lenses are unnecessary, as individuals with emmetropia do not experience refractive errors that require correction. Therefore, the assertion that corrective lenses are not needed aligns perfectly with the definition of emmetropia.
