Abstract: A magnifying device (100) with multiple magnifications including: an outer shell (10) forming a body of revolution with an axis of revolution (X-X) and having an inner cavity (5), a first lens (30) mounted at a first end (13) of said outer shell (10), and a second lens (20) capable of moving between a retracted position and an extended position in which said second lens (20) is superimposed on said first lens (30) so as to change the optical characteristics of the magnifying device (100).
