🔍👓 A magnifying glass is a handheld optical instrument that is used to enlarge the appearance of objects or text. It typically consists of a convex lens mounted in a frame with a handle, allowing the user to hold it up to their eye and focus on the desired subject. The magnifying glass helps enhance details and make small objects or fine print easier to see by increasing their apparent size. It is commonly used for tasks such as reading small text, examining fine details in objects, or conducting scientific observations.
