Correct answer and explanation

Correct answer: Concave lens

Explanation: āœ… Correct Answer: A) Concave lens šŸ“š Explanation: Myopia, or short-sightedness, is an eye defect where a person can see near objects clearly but distant objects appear blurry. This happens because the image of a distant object is formed in front of the retina instead of directly on it. A diverging concave lens is used to correctly shift the focal point back onto the retina.
