The defective condition of accomodation of the eye in which distant objects are seen distinctly but near objects are indistinct is

Options

A. Myopia
B. Astigamatism
C. Presbyopia
D. Hypermetropia.

Answer

To solve the question regarding the defective condition of accommodation of the eye where distant objects are seen distinctly but near objects are indistinct, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a condition where distant objects are seen clearly, but near objects are not. This indicates a specific type of vision defect.

2. **Identify the Types of Vision Defects**: There are two primary types of vision defects related to distance:
- **Myopia (Nearsightedness)**: In this condition, near objects are seen clearly, but distant objects are blurred.
- **Hypermetropia (Farsightedness)**: In this condition, distant objects are seen clearly, but near objects are blurred.

3. **Analyze the Options**:
- **Myopia**: Incorrect, as it allows clear vision of near objects but not distant ones.
- **Astigmatism**: Incorrect, as it causes blurred vision at all distances due to an irregular shape of the cornea or lens.
- **Presbyopia**: Incorrect, as it is a condition related to aging where the eye gradually loses the ability to focus on near objects.
- **Hypermetropia**: Correct, as it is characterized by clear vision of distant objects while near objects appear indistinct.

4. **Conclusion**: Based on the analysis, the correct answer to the question is **Hypermetropia**.

### Final Answer:
The defective condition of accommodation of the eye in which distant objects are seen distinctly but near objects are indistinct is **Hypermetropia**.
