भिंग ही बहिर्वक्र आकाराची काचेची चकती असून त्याचा उपयोग कोणत्याही वस्तूच्या प्रतिमेचे दृष्य रूप मोठे करण्यासाठी होतो.

A magnifying glass is a convex lens that is used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle. Beyond its primary function of magnification, this simple yet ingenious tool serves a variety of purposes. It can be employed to focus sunlight, harnessing the Sun's rays to create a concentrated hot spot at the lens's focus, which is often used for starting fires.
