PURPOSE: A magnifier of forming a stereo image is provided to form an image according to a user's eyesight by symmetrically forming a plurality of small-sized convex lenses having different refractive indexes on both sides of magnifying glasses. CONSTITUTION: A couple of lens protection rims(3,3') are installed around outer circumferences of magnifying glasses(4,4'). A plurality of small-sized convex lenses(5,6,7,5',6') having difference refractive indexes are formed on both sides of the magnifying glasses in order to form stereo focuses. A plurality of ceramic lens cases(1,1') are used for covering the magnifying glasses. Mirrors(2) are installed at both outer surfaces of the ceramic lens cases. A plurality of support bars(9) are formed to fix the ceramic lens cases. A linking hole(8) is formed in the magnifying glasses and the ceramic lens cases.
