A magnifying glass is useful because it allows an object to be brought closer to the eye than the normal near point. This primarily results in:
- 1infinite linear magnification precisely when the object is at the near point.
- 2a significant increase in the total angular field of view of the observer.
- 3the formation of a real, inverted, and highly magnified image on the retina.
- 4a larger visual angle being subtended by the object at the eye, allowing it to be viewed in greater detail.✓
