- AFor a person suffering from short-sight defect, the image of a distant object is focused behind the retina.
- BShort-sight defect can be corrected by a converging spectacle lens.
- CFor a person suffering from long-sight defect, the image of a near object is focused behind the retina.
- DLong-sight defect can be corrected by a diverging spectacle lens.
Explanation
In myopia (short sight) the image of a distant object forms in front of the retina and is corrected with a diverging (concave) lens, so statements A and B are wrong. In hypermetropia (long sight) the eyeball is too short, so the image of a near object focuses behind the retina, and it is corrected with a converging (convex) lens — so statement C is correct and D is wrong. Hence statement C is the correct one.
