Q1. Which lens is used to correct myopia (short-sightedness)?
Answer: Concave lens
Explanation: Myopia (short-sightedness) occurs when the eyeball is too long or the cornea too curved, causing parallel light rays to focus in front of the retina. A concave (diverging) lens diverges the incoming rays so that they converge correctly on the retina.
