Using lenses can indeed magnify a viewing area, but specific constraints must be considered. Achieving a 10:1 magnification from a 10-inch diameter area to a 1-inch image is complicated by the short object-image distance of only 2 inches. Real-world optics, including fresnel optics, may not accommodate the necessary incident angles for this setup. Therefore, while lens combinations can enhance viewing areas, practical limitations may prevent achieving the desired magnification in this scenario. Understanding geometrical optics is essential for finding viable solutions.
