Bausch & Lomb 2X Magna Rule Bar Magnifier/Ruler with Acrylic Lens 10 Inch Long

For those times you need help reading the printed page, the Magna-Rule from Bausch & Lomb doubles the height of letters. It lies flat on the page and magnifies two lines of type at a time without any need to focus. The 10" overall length offers an 8" scale in both inches and centimeters, making it very useful with tabulated data. The Magna-Rule also serves as a linear guide, so there's no need to squint and struggle. Magnifier Type: Ruler; Lens Magnification: 2X.
