Abstract
A magnified viewer capable of viewing an information card or sheet supported on a support base of the viewer. The viewer includes a magnifying lens supported above the support base by means of two oppositely disposed side portions. The side portions are each attached at one end to the support base by a first set of hinges, and at their opposite ends to the magnifying lens by a second pair of hinges. Since the side portions are pivotably connected to both the support base and the viewing lens, the user of the viewer can readily scan the magnifying lens across the information card by merely tilting the side portions from one side to another.
