Model Answer
(i) In a hypermetropic eye, the image of a nearby object is formed behind (beyond) the retina instead of on it.
(ii) A convex (converging) lens is used for correction. It provides the additional converging power needed, bringing the image forward onto the retina so the person can see nearby objects clearly.

Explanation
- Examiners want both parts answered distinctly — don't merge them.
- Key phrase for (i): "behind/beyond the retina" — not "in front."
- For (ii): name the lens and state its action (converges light / adds focusing power → image falls on retina). One without the other loses a mark.
- Avoid vague phrases like "helps see better" — always link to image falling on the retina.
