    The medical term for farsightedness is:

    • Presbyopia

    • Myopia

    • Hyperopia

    • Asthenopia

    Correct Answer
    A. Hyperopia
    Explanation
    Hyperopia, also known as farsightedness, is a condition where individuals have difficulty focusing on close objects. This occurs when the eyeball is shorter than normal or the cornea is too flat, causing light to focus behind the retina instead of directly on it. As a result, near objects appear blurry while distant objects are clearer. Presbyopia is a condition that occurs with age, causing difficulty in focusing on close objects. Myopia, also known as nearsightedness, is the opposite of hyperopia, where individuals have difficulty seeing distant objects clearly. Asthenopia refers to eye strain or fatigue.
