Handheld magnifying glass, as a portable and practical optical tool, is widely loved by users. It is usually designed to be small and lightweight, making it convenient for users to observe anytime, anywhere. The magnifying glass also has some special application scenarios. For example, in jewelry appraisal, a professional jewelry magnifying glass can help appraisers observe the internal structure, color, and clarity of gemstones more clearly; In photography, photographers can use a magnifying glass as an auxiliary tool for macro photography, taking detailed macro photos.

A magnifying glass, also known as a convex lens, is a simple optical device used to observe small details of an object. Its main feature is that the middle is thick and the edges are thin, which allows light to refract when passing through it, thereby achieving an amplification effect. A magnifying glass is a powerful optical device that opens the door to the microscopic world with its unique amplification function, allowing us to observe details that are difficult to detect with the naked eye.
