Explanation:

- Myopia is a vision condition in which close objects are seen clearly, but distant objects appear blurred.

- Option 1: Near-sightedness (also known as myopia) is the correct term, as it refers to this condition.

- Option 2: Astigmatism is a different condition caused by an irregularly shaped cornea or lens. It results in blurred or distorted vision at all distances.

- Option 3: Presbyopia is age-related farsightedness that typically occurs in middle and older age, characterized by difficulty in seeing close objects.

- Option 4: Far-sightedness is also known as hyperopia, where distant objects may be seen more clearly than close ones.
