The lens used to correct long sightedness or hypermetropla.
- A. Convex lens
- B. Concave lens
- C. simple lens
- D. Cylindrical lens
Step-by-step solution
Hypermetropia (long-sightedness) occurs when the eye focuses images behind the retina. A convex lens converges light rays before they enter the eye, thereby shifting the focal point forward onto the retina, correcting the defect.
