As the size of the image is bigger than the size of the object
and angular size of image is equal to angular size of object.
we use magnifying glass to see the objects placed closer than the least distance of distinct vision 25cm
A closer object produces a greater angular size.
A magnifying glass provides angular magnification.
with magnification, object can be placed much closer to the eye
