The correct Answer is:
To determine which statement is correct regarding myopia and hypermetropia, we will analyze each statement step by step. ### Step 1: Understand Myopia - **Definition**: Myopia, or nearsightedness, is a condition where a person can see nearby objects clearly but has difficulty seeing distant objects. - **Cause**: In myopia, the eye's lens has too much converging power, which means it bends light rays too much. This occurs because the ciliary muscles contract but cannot relax properly, leading to a decreased focal length. **Hint**: Remember that myopia affects the ability to see distant objects clearly. ### Step 2: Analyze the First Statement - **Statement**: "Person with myopia can see distant objects." - **Evaluation**: This statement is incorrect because individuals with myopia struggle to see distant objects clearly due to the excessive converging power of their lenses. **Hint**: Think about how the eye's lens functions differently for near and far objects. ### Step 3: Understand Hypermetropia - **Definition**: Hypermetropia, or farsightedness, is a condition where a person can see distant objects clearly but has difficulty seeing nearby objects. - **Cause**: In hypermetropia, the eye's lens has too little converging power, which means it does not bend light rays sufficiently. This occurs because the ciliary muscles are weak and cannot contract effectively. **Hint**: Consider how the eye's lens needs to adjust for different distances and how hypermetropia affects this. ### Step 4: Analyze the Second Statement - **Statement**: "Person with hypermetropia can see nearby objects clearly." - **Evaluation**: This statement is also incorrect because individuals with hypermetropia have difficulty seeing nearby objects due to insufficient converging power. **Hint**: Recall the relationship between the strength of the eye's lens and the distance of the object being viewed. ### Step 5: Analyze the Third Statement - **Statement**: "Person with myopia can see nearby objects clearly." - **Evaluation**: This statement is correct. Individuals with myopia can see nearby objects clearly because their lenses have the appropriate converging power for close objects. **Hint**: Focus on how myopia specifically affects vision for nearby versus distant objects. ### Step 6: Analyze the Fourth Statement - **Statement**: "Person with hypermetropia cannot see distant objects clearly." - **Evaluation**: This statement is incorrect. Individuals with hypermetropia can see distant objects clearly because their lenses have less converging power, which is suitable for viewing faraway objects. **Hint**: Think about how the eye's lens needs to function for distant vision in hypermetropia. ### Conclusion After analyzing all the statements, the correct answer is: - **Correct Statement**: "Person with myopia can see nearby objects clearly."
