First magnifying devices were known to man roughly 500 years BC. Glass lenses were utilized to start a fire, while glass flasks filled with liquid were used to magnify text. In the heart of a modern-day magnifying tool lies a convex lens. These lenses vary by magnification rate, commonly set within borders of 2-6 times magnification. Loupes commonly have a higher rate (up to 30x), and are mounted, as mentioned above, on glasses to provide an instant enlarged image without distracting the user. Headgear with retractable loupes or even several sets of loupes with varying magnification rate is also common.
