Expert Answer:

In case of correction to a myopic eye, the object to be seen is at infinity ad its image is to be formed at the far point, so u = infinity and v = distance of far point.
In case of correction to a hypermetropic eye, the object is at least distance of distinct vision of normal eye and its image is to be seen at near point of defective eye, so u = distance of near point of normal eye and v = distance of near point of defective eye.
