Long-sightedness is to hypermetropia as short-sightedness is to

Options

A. myopia
B. focusing
C. astigmatism
D. accommodation

Explanation

To solve the question, "Long-sightedness is to hypermetropia as short-sightedness is to," we can follow these steps:

### Step 1: Understand the Terms
- **Long-sightedness** is also known as **hypermetropia**. This condition occurs when distant objects are seen clearly, but nearby objects appear blurry.
- **Short-sightedness**, on the other hand, is the inability to see distant objects clearly while nearby objects can be seen clearly.

### Step 2: Identify the Condition for Short-sightedness
- The medical term for short-sightedness is **myopia**. In this condition, the eye focuses images in front of the retina, making distant objects appear blurry.

### Step 3: Establish the Relationship
- The relationship in the question is that long-sightedness (hypermetropia) is paired with its corresponding term, and we need to find the corresponding term for short-sightedness.

### Step 4: Conclusion
- Therefore, the answer to the question is that short-sightedness is to **myopia**.

### Final Answer:
Long-sightedness is to hypermetropia as short-sightedness is to myopia.
