Diagnosing Vision Problems: Blurred Distance Vision

The question describes a specific vision impairment where a person struggles to see objects located farther away clearly, while objects held close, like a book, are easily visible.

Identifying the Eye Defect

This pattern of vision difficulty points to a refractive error. Let's consider the common eye conditions:

• Myopia (Nearsightedness): This condition occurs when the eye focuses images in front of the retina instead of on it. As a result, distant objects appear blurry, but near objects are seen clearly.
• Hypermetropia (Farsightedness): In this condition, the eye focuses images behind the retina. Near objects appear blurry, while distant objects are typically seen more clearly (though severe cases can affect both).
• Astigmatism: This defect arises from an irregularly shaped cornea or lens, causing blurred or distorted vision at all distances.
• Presbyopia: This is an age-related condition where the eye's lens loses flexibility, making it difficult to focus on near objects. It primarily affects close-up vision clarity.

Conclusion on Vision Defect

The student's inability to see distant objects clearly, coupled with the ability to read comfortably, perfectly matches the definition of myopia.
