Reading glasses use converging lenses. A simple magnifier is also a converging lens. Are reading glasses therefore magnifiers? Discuss the similarities and differences between converging lenses as used for these two different purposes.
Step 1 of 1
The differences between a magnifier and the reading glasses are:
(1) Both the magnifiers as well as the reading glasses are made of converging lenses.
(2) In a magnifier, a virtual image of the object is formed when the object is placed at the focal point whereas in the case of reading glasses the rays of light are made to converge on the retina when the object is at the least distance of distinct vision that is 25 cm.
(3) In the case of the magnifier, focusing of the object is done by moving the lens. Whereas in the case of reading glasses, the lens is not moved but the eye lens adjusts its shape to change the focal length of the lens. The glasses just shift the objects which produce virtual images and focus the light rays into the retina.
