2 Pack Full Page 3X Magnifier/Plastic Magnifying Sheet Fresnel Lens, 2 Count (Pack of 1)

Please Note: These lenses must be held several inches above the page to produce a magnified image. They do not magnify when placed directly on a surface. The level of magnification increases gradually as the lens is raised higher above the page. Maximum magnification occurs around ten inches from the surface. Therefore, they are not recommended for use with computer monitors or for reading music sheets, as the lens would need to be positioned a sufficient distance from the surface to work. (2) Pack of Large 7" x 10" Fresnel Lens Magnifying Sheets by OpticLens. They are designed for reading fine print in books, magazines, newspapers, maps, menus, and recipes. They are also suitable for light-duty solar projects, such as starting campfires, solar cooking, and solar heating. They can also be used for light-focusing applications, such as classroom solar experiments and demonstrations. Made from flexible, optical-grade PVC for durability and ease of handling. The lenses can be trimmed to a smaller size or shape using a paper cutter or sharp scissors.
