Magnifiers are optical devices that enlarge the appearance of objects, making them easier to see. They typically consist of a convex lens, which bends light to create a larger image. Magnifiers are commonly used in various fields, including medicine, electronics, and crafts, to assist with detailed work or reading small text. These tools come in various forms, such as handheld magnifying glasses, magnifying lamps, and digital magnifiers. They are especially helpful for individuals with vision impairments, allowing them to read books, examine small parts, or enjoy hobbies that require close attention to detail.
