10 Diopter / Magnification Diopter (d): A term used to identify the refractive (light bending) capacity of a lens. In magnifiers, there is a direct correlation between focal length and diopter. Each diopter increases the size of the viewed object by 1/4 (25%) when the object is at its full focal length from the lens. Field of View: The distance across the lens surface to which the viewer brings his/her eye/s. It is important to note that as magnification increases, meaning the lenses used are stronger, viewing areas and focal length decrease. Magnification: The degree to which the viewed object is enlarged. Magnification is usually expressed by a number followed by an x, the symbol used to express power or the size of the object in relationship to its actual size. The formula for calculation Magnification Power is: Common diopter/power relationships Power % Bigger than Focal object Length X 75% 330mm X 100% 250mm X 125% 200mm X 175% 140mm X 200% 127mm X 225% 114mm X 275% 95mm X 325% 76mm X 400% 63mm X 450% 57mm X 500% 50mm Selecting The Right Magnifier: Determine the desired magnification for your needs. Remember, as you increase magnification, you decrease both the focal length and the viewing area. Note the focal length and lens diameter that correspond to the magnification and lens diopter you have chosen, and make sure they are suitable for your task. As a general rule, because the working distance will be less than 20cm above 5 diopter. Tips on Proper use of a Magnifier To take best advantage of the comforts built into illuminated magnifiers please keep these points in mind: 1. Use both eyes. Magnifiers are designed as working tools. They can be used as comfortably as a pair of glasses. 2. Position the lens so that it is a proper distance from the work area, yet close enough for your eyes (20 to 25cm) so that you have the maximum magnification without distortion. Do not lean back away from the lens to increase magnification. 3. Chair height and work surface should be positioned so the operator can maintain good
