SIZE VS. POWER IN MAGNIFIERS :
A perfect magnifier would be lightweight, have a large diameter, provide a wide viewing area, and offer high, distortion-free magnification. However, incorporating all of these features into one unit is optically impossible. The magnifying power of a lens depends on its focal length (fl). The focal length, in turn, depends on the lens curvature; the greater the curvature, the shorter the focal length and the greater the power. In the design of a simple, inexpensive magnifier, the lens diameter will typically decrease as the curvature increases to provide higher power. Conversely, as the curvature is decreased to lower the power, the diameter generally increases with a resulting increase in viewing area. In addition, distortion generally increases with an increase in curvature. Thus, a magnifier with a large diameter typically offers more viewing area and less power. So, both wide field of view and high magnifying power cannot be incorporated into a single design without elaborate, weighty, high-cost lenses.
