What condition involves a need for correction to improve focus for both distance and near vision?

The condition that involves a need for correction to improve focus for both distance and near vision is hyperopia. Hyperopia, or farsightedness, occurs when the eyeball is too short or the cornea has too little curvature. This results in difficulty focusing on close objects while often enabling clearer vision for distant objects.

In many cases, individuals with hyperopia may require corrective lenses that help them focus clearly on near objects, which can enhance their overall visual capacity for both near and distant tasks. Over time, as the eye’s ability to accommodate diminishes—particularly with age—hyperopia can lead to increased strain and discomfort when performing tasks that require close vision, necessitating corrective lenses.

Myopia (nearsightedness) primarily affects distance vision, presbyopia is an age-related condition that affects near vision, and astigmatism causes blurred vision due to an irregular shape of the cornea or lens. While presbyopia may lead to difficulties with near vision, it does not typically require correction for distanced vision with the same lens type, making hyperopia the most applicable condition involving correction for both focus types.
