A magnifying glass is used, as the object to be viewed can be brought closer to the eye than the normal near point. This results in 

(a) a larger angle to be subtended by the object at the eye and hence viewed in greater detail. 

(b) the formation of a virtual erect image. 

(c) increase in the field of view. 

(d) infinite magnification at the near point.
