Short-sightedness can be corrected by using ___________?
- A. Convex lens
- B. Concave lens
- C. Convex-concave lens

Explanation
In myopia, distant images focus in front of the retina, often because the eyeball is too long or the lens is too strong. A concave lens spreads incoming rays so the image shifts back onto the retina.
