• A. Concave, concave
• B. Convex, convex
• C. Convex, concave
• D. Concave, convex

Answer 1

The correct option is D Concave, convex

Myopia means short-sightedness, in this, a person has a clear vision when looking at objects close to them, but distant objects will appear blurred, to correct it easily concave lens is placed in front of a myopic eye, moving the image back to the retina and clarifying the image.

Hypermetropia means long sight in which a person have blurred vision when looking at objects close to them, and clearer vision when looking at objects in the distance. By placing a convex lens in front of a hypermetropic eye, the image is moved forward and focuses correctly on the retina.
