Option 2: lenses with negative
Option 3: concave lenses
Option 4: convex lenses
Correct Answer: convex lenses
Solution : The correct option is convex lenses.
Long-sightedness prescription glasses include convex lenses, which fix the light entering the eye by slightly bending the light rays inward, ensuring they fall at the right point on the retina. The centre of a convex lens, also known as a converging lens, is thicker. Through a convex lens, light rays converge.
