In viewing through a magnifying glass, one usually positions one's eyes very close to the lens. Does angular magnification change if the eye is moved back?

Class: Class 12 Subject: Physics Topic: Ray optics and optical Instruments

Yes, the angular magnification varies. 

When the length between the eye and a magnifying glass rises, the angular magnification reduces slightly because the subtended angle at the eye is imperceptibly less than the lenses. 

Image distance does not have any impact on angular magnification.
