The hyper-metropia is a

AShort-side defect
BLong-side defect
Correct Answer
CBad vision due to old age
DNone of these

Solution

The hyper-metropia is an eye defect when person faces difficulty in seeing nearby objects(Short Sight) but not far-sided objects (Long Sight). Due to inability of the eye lens to converge light rays from nearby objects at the retina, image is formed behind the retina. Long sight leads to problems with near vision. So hyper-metropia is a Long-side defect.
