Explanation:

- Myopia (Option 1): Also known as nearsightedness. Far objects appear blurry since the eye focuses images in front of the retina.

- Hypermetropia (Option 2): Known as farsightedness. Nearby objects become blurry because the images focus behind the retina.

- Presbyopia (Option 3): Age-related vision defect. The eye's lens loses flexibility, making it hard to focus on close objects.

- Cataract (Option 4): A condition where the eye's lens becomes cloudy. It affects vision quality but is not related to the eye's refractive ability. ?

Correct Answer: Option 4 - Cataract
