magnifying glasses and loupes are optical devices used to magnify small objects or details. Magnifying glasses are simple lenses, typically with a convex shape, that enlarge the object being viewed. They are often used for reading small print or examining small objects such as jewelry or coins. Loupes, on the other hand, are more powerful magnifying devices that are often used in specialized fields such as dentistry, jewelry making, watchmaking, and surgery. They consist of a set of lenses arranged in a specific way to provide higher magnification and better image quality than magnifying glasses. Some loupes may be attached to glasses or worn as a headband for hands-free use.

Both magnifying glasses and loupes are useful tools for tasks that require precision and attention to detail.
