A person suffering from hypermetropia (farsightedness) uses corrective lenses. Which type of lens is typically prescribed, and where does the image of a nearby object form without correction?

Accepted Answer

C. Convex lens; image forms behind the retina. — Hypermetropia, or farsightedness, occurs when the eye's lens or cornea is unable to converge light sufficiently, causing light rays from nearby objects to focus at a point behind the retina.

This lens helps to increase the convergence of light rays before they enter the eye, ensuring they focus correctly on the retina for clear vision.
