It consists of a handle and a circular lens, which helps users see fine details that are difficult to discern with the naked eye. Magnifying glasses are commonly used in various fields, including science, art, and crafts. These tools are especially helpful for activities like reading small print, examining intricate designs, or studying small specimens in biology. They come in various sizes and strengths, making them versatile for different tasks. Magnifying glasses are often used by hobbyists, students, and professionals alike.
